42 Troubleshooting call termination problems

Prerequisites

• "Call termination problem scenario setup" (page 38)

Procedure steps

Step Action

1 In the packet capture, look for the INVITE message from the

UEXT.

If the INVITE message is not present, check the configuration of

the device on the call server.

3 Look for the 180 ringing message from the call server to

the gateway and determine if the gateway sends the 200 OK

message to the client.

4 If the 200 OK message does not appear, check the configuration

of the client on the gateway.

5 Look for an HTTP POST request with the user’s phone number

that the Avaya 3100 Mobile Communicator - Client user

requested to answer the call.

6 If an HTTP POST request is not available with the user’s phone

number, check the configuration of the client on the gateway.

In the packet capture, look for the INVITE message from the

Avaya 3100 Mobile Communicator Gateway to the answer

destination.

8 If the INVITE message is not present, check the configuration of

the client.

9 In the packet capture, look for the INVITE message from the

UEXT contains the correct Request URI.

If the INVITE message from the UEXT does not contain the

correct Request URI, check the configuration of the URI.

Look for a valid dialable number that the user is trying to answer.

12 If the calling number is not valid, check the configuration of the

calling number.

13 If the problem is intermittent, look for the difference between a

trace that works and one that does not. It may indicate a Firewall

policy issue for a port.

14 If the problem is not intermittent, send the scenario,

configuration, packet captures, and logs to Avaya for analysis.
