【Phenomenon description】
Run lights flashing slowly (flash once per second), you will hear the object dont of the net break, it means that the EIA cannot register online.
【Solution】
1.
1. Physical connection fault
First connect twisted-pair cable through the gateways, and make sure that the physical connection is still work through the Netcard of the gateway device and the indicating lamp of Hub or switch. . If the port of the gateway equipments and Switches corresponding port doesn’t bright when the gateway equipments are electrify, it means physical connection is failure.
Please make sure that twisted-pair between the gateway and the switch do not loose when the gateway and the switch equipment are electrify, and then compare to determine the quality of RJ45 or twisted-pair of the gateway and switch equipment., now in general, the equipments are below the exchange equipment and the Hub and switches have the function of jump line automatically, so don't consider the type of network cable, if you connect to the computer directly ,you should notice the type of the cable .
2. Gateway IP address setting fault
The IP address setting, the gateway supports assigning IP addresses in two ways: static and dynamic allocation, (specific methods can refer the setting configuration below the equipment), After do that , you can check out the IP address of the equipment by using *158 ,if the prompting message is your IP address is XXX. XXX. XXX. XXX, it means that you get IP address success, instead of that, if the prompting message is: your IP address is 0.0.0.0, it means that the gateway equipment didn’t acquire the IP address.
If the network connection is OK, but it still appears the fault above, usually it maybe have the following two aspects problems:
a)
If the IP address is assigned by DHCP, check the DHAP server whether it is working normally and whether there exist the residual address space. We should seek support of the network administrator to check the network router and DHCP server.
b) Static setting, to check that whether the setting method is correct, please reset it if it is incorrect (specific setting method can refer to the equipment user manual)...
3.
Local network connecting fault
After the device get the IP address, we can check the communication between the computer and network, in use of the methods like Ping, Telnet and web.
If the equipment can obtain IP address in use of DHCP way, network is usually normal, but sometimes it is set manually, querying the IP address doesn't mean the communication between the equipment and network are properly.
Ping xxx.xxx.xxx.xxx（request time out ）
Telnet xxx.xxx.xxx.xxx（connect failed）
Http://xxx.xxx.xxx.xxx（无法显示该页）
If the contents of the brackets exist when you do the operation above, maybe the communication between equipment and network are not so good, or this service are abandon in the net(this situation is unusual. the above content, operating appear brackets may have impeded or equipment and network communication network to ban the service (but the situation is rare). Or there is no right parameter of equipment IP, gateways, subnet mask, etc.。
4 wrong setting of Fault platform data
We can check the related parameters of EIA equipments which are set on the platform.
a)
a) Check whether the data of the platform are conform to the MAC of the gateway equipment, which is easily ignored.
b)
b) If the data is not setting or the error of data setting is found, to add equipment again or modify the configuration data error.
5. firewall fault Settings
Today, many companies are equipped with the network firewall, confirm whether the customer network has firewall, such as firewalls are equipped to do the following operation, it is suggested that customer should open the related conditions of EIA equipment.
EIA gateway in teh firewall can be soluted by the following methods
a)
Open port. Due to the EIA gateway equipment involves too many port, incomplete open port may cause the puzzling problem, such as bad sound quality and single-pass .suggest do not use the open port (if the customers need to open port, specific consulting company technical personnel).
b)Open protocols ( the protocol of EIA equipment we are using is UDP )
c)
Open IP address (the IP address we refer is address acquired by voice gateway equipment, specific address can dial up in the telephone 158 #) (recommended!)
Use tunnel
Attention!
Some customers think that open these parameters may bring the network unsafe hidden .but open port, agreement, IP address we mentioned, is in EIA gateway equipment operation, and not let customer network all open.
6.
EIA local data configuration fault
Through the above steps, if you still can not register, the problem may be the setting of the IP address of local gateway call center and port.
We use telephone to dial out equipment * 158 in the EIA gateway equipment, and to check out the IP address, and then entered into the gateway WEB pages through the IE, entered into the EIA setting page, in call center, choose static IP, re-write the IP address and port of platform, save it, restart gateway equipments.
Attention!
In setting process, if clew operating errors, then you should check the parameters to make sure that it is set correctly, if it is still clewed, may be the equipment is locked (new equipment platform rarely appear this kind of circumstance).
7.
Network access fault
Now the Internet Shared access main have three methods: routing, NAT and agent, we can use the EIA equipment route and NAT directly. We need some Settings if we use the method of agent. In these three ways, network routing is general rarely used .we main use NAT and proxy server, if it is used as the NAT way, As long as the IP address are not contained by the gateway equipment， it can be connected to the Internet through NAT directly. If the agency is to set a proxy server's IP address and port, check the following aspects when it is not able to use normally:
If the customer network uses agent server, we should get into the configure page of the gateway through the WEB, setting the IP address of agent server and related parameters of agent port.
a) a) To ensure that the function of network agent server in the gateway works normally.
b)
b) Zhongfang has tested the agent servers which are used on the market, and ensure that all of them can be used normally; you should consult the service if you use the other agent servers’ software.
8.
Network interconnection fault
The communication problems of internet, which cause the user cannot connect to the normal equipment, it usually displays that the setting of equipment connection and platform data is have no problem, but the equipment is not able to registered to platform, then the customers should check the problem of connection between the net and platform.
Users can use the Ping command platform IP address to see if it is timeout, notice that some network is use of static ICMP protocol, but this operation can only for reference. The user can see the answer through the other network. Consult your local network operators and let them do the test for you.
9.Gateway equipment physical breakdowns
Through the above fault, make sure that it is no problem, should notice that whether the gateway devices exist physical breakdown, we can estimates whether the devices have the physical problems through the power supply of observe device and the indicate lights, to get the company for technical support, if it is the physical breakdown, you have to return the company to get the physical repairs.

【Phenomenon description】
Lights flash fast after a period of slowly, the equipment restart repeatedly and cannot call up.
【Solution】
1. the IP address conflicts
If the IP address the device acquired is conflict with the IP address of the other devices in the LAN, it can solute out by change the IP address of EIA equipment to the useless one, maybe the ADSL connected by router often break and dial again, and the renewal term of IP address is very short, EIA often alter the IP address, Suggest the EIA default mode is set to the fixed IP address, avoid the confliction with DHCP.
The single-pass between the network of the EIA equipment and the register server.
We can solve it by trying to reset the router. Because the interconnection between network communications may not work, maybe the reset routers can not solve this problem.
3.
The high-end UDP port is blocked (by network operator or local firewall).
Routers have the problem of the connection among the ports 5000 above, UDP communication problem; we can change the MGCP port from 20002 to 2200, and move down the default port. |

【Phenomenon description】
The run lights flash quickly after EIA access to the network, it means you have already registered to the platform, but we can not hear any sound or the sound we hear is busy tone when we hold off.
【Solution】
1.
1. Please login in the web management interface of EIA registered platform, check the EIA, you will hear the busy tone when you hold off.
2.
2. If you ensure that the EIA are working, please check the type of EIA to make sure that the setting is correct. Configuring the equipment 4S to 2S, or configuring the S to O, can cause corresponding port would not be able to call.
3.
3. If the EIA equipment management data are setting correct, we should check the data setting of FXS port, first makes sure that the ports which telephone corresponds are configured short number. , The S port without configure short number will exist busy tone when we hold off.
4.4. See the "customer form" of S port; it can’t be telephoned normally if the setting is “stop”.
5.
5. There may be another sitution that the customer sets the substitution number in S port, if this number is not a complete legal number, when the user pick up, the system will dial these numbers first, and then wait for the user continue to dial, at that time ,there are no sounds when picked up.
6. if the port configure the user group of PBX, to check whether it is correct. If the calling party inbounds is FXO port, it need to check whether the FXO port of call for "just exhale," if the answer is yes, all incoming were refused.
7. out of all the above reasons, another possibility is IP conflict, if the IP of EIA and the IP of another computer and devices in LAN has the same setting, it will cause IP conflict, in IP conflict, EIA may online normally at intervals, appears the run light flash quickly, sometimes can telephone, but sometimes can’t heard anything when pick up, please reset another IP without any conflict and then try it again.
8. If you cannot find out the problem after you test according to the above steps, please consult the maintenance personnel of Zhongfang Company or its agent company .

【Phenomenon description】
The system prompt that “the number you called is not exist”, when you dial.
【Solution】
1.
First, the user can judge the prompt from EIX platform or from switch of PSTN (e.g., Netcom, Rail COM, etc), if it comes from floor pattern telephone switchboard, we can judge that the EIX platform parse the number into the number point to face. The user must check the number you dialed to ensure that it is the number point to face, if the number is point to face, check it carefully to be correct. For example, if you dial the number 02885335820 mistaken for 85335802, While the latter does not exist or haven’t enabled, the room will tip "the number you called does not exist."
2.
If the costumer ensure that the number he dialed is correct, and then he should check the user group data setting of the port correspond, two of which mast pay attention to:
First is the "rules", the system allows the costumers choose or customize the dial-up rulers according to their own habit, there are two options can be chosen. 1
、the default dial-up rules: this rule is the dial up styles combine with VIOP point to face +IP PBX internal call, which is recommended by system. Generally this option should be chosen: 2
、 custom dialer rules: the rule is used by the costumers with special requirements; the rules need to be realized by setting "call-routing in group”. Generally we don’t recommend that users choose this option, if the users choose it, and don't know the correct method of setting, it may cause dial-up error easily.
Second is IDD telephone, the users who choose “default telephone rules” can custom dial-up styles of IDD telephone by setting these properties. Setting these properties may influence the dial rules of the whole group. if select" yes ", users must dial point-to-point telephone begin with #, if select “no”, then point to face will call by add the area code. Local telephone needn’t begin with #, the default style of the system is indirect way.
3.
If t two aspects above are of no problem, then we should ensure that whether it set the substitute number in the corresponding port data,, if set the substitute number like ‘028’,then all the number the user calls will add “028”,then it will cause dial-up error.
If you cannot find out the problem after you test according to the above steps, the problem may cause by the error of device transceiver number, please consult the maintenance personnel of Zhongfang Company or its agent company.

【Phenomenon description】
Some point-to-point number couldn't get through
【Solution】
1. Make sure that the device is working in WEB configuration interface.
2. Do not have configuration port and port configuration is not correct.
3. Check whether the equipment is forbidden in WEB configuration interface.
4. Check whether the short number you dialed exists.
5. Check whether the users are in the same group and the group is IDD telephone.
6. If you are prompted that the number you dialed is on fault, maybe the equipment on the other side is not online, it can dialed up when the equipment is online.
7. The system clew you that the number you dialed does not exist, most of these are dialed according to the dial rule of cross group. The correct way of dial is: “# +group number +# + short number, or call the TT number of the other side.
8. If you heard that the network is busy after dialing the number, you should check that whether it create the Trunk Group in the user group, and whether the Location Routing Number of O port are reduplicate with the front of the called number.
9. If you can exclude the above problems, please contact the technical support staff. |
|
【Phenomenon description】
1.
Prompt that "Please don't add “0” at the beginning of the local number! ".
2.
"The number you dialed does not exist, please add “0” at the beginning of the telephone number, but if you added “0”, there are nothing changed.
3.
You will hear the busy tone or the prompt that the number you dialed does not exist.
【Solution】
This situation can be Signal trace by technical support staff to ensure the problem. Through the signal trace, we can see the number the used dialed, and check whether the number received is normal.
The first problem can be solved by technical support staff to check that whether the number is contained in the local phone number section list and check that whether the number is belong to the local phone number, if it is not the local phone number, but it exist in the mobile platform number section list, please modify this record, the second and the third problems may be solute by the technical personnel to feedback to the operators. |

【Phenomenon description】
1. Domestic long distance can get through, but the aboard can not get through.
２.2. Some fixed telephone can not get through, it promote that “the number you dialed does not exist”, or “the number you dialed can not get through”, or you can hear the busy tone after dialed.
【Solution】
1. First check the equipment whether the domestic or international long distance are forbidden, if you exclude the problem above, you should check that whether it create the Trunk Group in the user group, and whether the Location Routing Number of FXO port are reduplicate with the front of the called number.If you exclude the problems above, please contact the technical support staff .They will feedback the problem to the computer room and solute it out. |

【Phenomenon description】
Hearing the prompt that “the calling is restrict, please use it beyond the power.”
【solution】
Make sure that whether the port has the power of inner and inter group calling. this phenomenon often caused by calling cross the groups, the correct calling way is # + group number + # + short number; Confirm that whether the short number called by user are conflict with the choose number of the FXO Trunk Group in the user group, and the Trunk group has the setting of calling constrict. |

【Phenomenon description:】
Hearing the prompt: “the number you dialed has the line fault”
【solution】
The EIA you called is not on line, it will be OK when the EIA is on line. |
|
【Phenomenon description】
Hearing the prompt that:” the number you dialed can not get through.”
【Solution 】
Switch is in busy, there are no resources available, or call transfer to point to face, or the user who enable the call transfer has no money available in his card. | |
