1. The outgoing phone number in the room is repeated, which is the number within another MA5620.

Idea: first confirm the configuration on MA5620, then query the configuration of U1960

Solution: relay configuration on U19 the second board in AT0 does not have a number configured with the corresponding line sequence

two。 The phone on the new U19 device communicates with the phone in the new device, and the voice can only be heard by one side.

Idea: first confirm that the situation is between the new number and the new number, between the new number and the old number, between the old number and the old number, and then

The discovery will only happen between the old number and the new number. Seek the help of the manufacturer and find that the network between the devices is not connected.

Solution: the gpon device is not connected to 5620 of the network because the voice vlan103 is not configured with arp proxy

3. There will be a call back after the phone hangs up, and the number is 000 after grabbing the bag.

Idea: is there any problem at the telecom end, is there any similar service, and then find that the number where this problem occurs is fixed, then check the configuration of U1960?

However, after seeking the help of a senior engineer, I found that the AT0 line of U1960 was not fully configured.

Solution: the at0 dedicated line on U1960 is full.

4. The phone can not be dialed, and it will be fine again after a period of time. The time is very short. One minute to two minutes.

Idea: first eliminate the configuration problem, the approximate direction is the line problem or number conflict, and then eliminate the optical path problem with the help of the manufacturer, and then determine the number registration conflict by finding that the voice IP is different when the problem occurs.

Solution: there is a conflict in telephone registration. If the other party's device cannot be found, authenticate the number to avoid recurrence.

5. When the mobile phone dials the number, the phone does not ring and there is no abnormal sound when answered by the mobile phone. The short account dials the question number and indicates that the number is wrong, but there is no problem with the trombone and short account dialing.

Idea: first make sure there is no telecom problem, then query the u1960 call log, and find that when the calling number is a mobile phone, the called number is displayed as a short number, and then check the relevant configuration of the short number.

Solution: it is found that there is the same trumpet on the prefix configuration of two U19s. After deleting one, the problem is solved.

6. When the mobile phone dials the number, it will hang up automatically. The trumpet can be dialed to each other without showing.

Idea: first determine whether the telecom has to be displayed, whether it can be dialed, and then check the relevant configuration on u1960, especially the trumpet configuration. When there is a display on the distribution frame, the replacement phone is tested again, and it is found that it is a phone problem.

Solution: change the phone

7. When the mobile phone dials the number, the phone does not ring and there is no abnormal sound when answered by the mobile phone. There is no problem with inter-account broadcasting.

Idea: first determine whether there is a problem with telecommunications. When there is no problem, check the configuration and find that the topology is different. For the telecom distribution frame-> IAD-- > u1960muri-> gpon, check step by step, unable to find the incoming call in the u1960 log, and then do a port mirror on the IAD to grab the packet. It is found that the incoming phone has no data entry at all. Rethinking for the problem of circuit

Solution: replace it with AT0, do dedicated line, and solve the problem.

8. The number calls the mobile phone to remind the user that the user is busy, there is no problem with the long and short accounts in the bureau, and there is no problem with the mobile phone dialing the number (the problem disappears after a period of time)

Idea: first determine whether there is a problem with telecommunications. After there is no problem, register with openeye to test if there is a problem, then re-register or reset on gpon, and then replace the device or line

Solution: gpon device re-registration, problem resolution

9. The number calls the mobile phone to remind the user that the user is busy, there is no problem with the long and short accounts in the bureau, and there is no problem with the mobile phone dialing the number (the problem always exists).

Idea: first determine whether there is a problem with telecommunications. After there is no problem, register with openeye, find that the problem still exists, and grab the package.

Grab the packet found that the number 3493 is equipped with a call source of 1, while call source 1 is equipped with a call source route, and when the local selection code 0 is out, the local 1 is selected. But 3493 equipped with AT0 direct dial trunk, is under the local direction of 0.

In this way, U1900 made a mistake in line selection: according to the call source route, it was supposed to choose local direction 1, but under local direction 1, the direct dialed AT0 trunk could not be found, so the line selection failed.

Solution: enter config modify subscriber dn 3493 callsourceno 0 / / under the corresponding u1960 / modify the call source for the user to be 0
