6. Verification and Troubleshooting

This section provides verification steps that may be performed in the field to verify that the

solution is configured properly. This section also provides a list of useful commands that can be

used to troubleshoot the solution.

6.1. Verification Steps

The following activities are made to each test scenario:

Verify that endpoints at the enterprise site can place calls to PSTN and that the call

remains active for more than 35 seconds. This time period is included to verify that

proper routing of the SIP messaging has satisfied SIP protocol timers.

Verify that endpoints at the enterprise site can receive calls from PSTN and that the call

can remain active for more than 35 seconds.

Verify that the user on PSTN can end an active call by hanging up.

Verify that an endpoint at the enterprise site can end an active call by hanging up.

6.2. Protocol Traces

The following SIP message headers are inspected using sniffer traces:

Request-URI: Verify the request number and the SIP domain.

From: Verify the display name and display number.

To: Verify the display name and display number.

P-Asserted-Identity: Verify the display name and display number.

Privacy: Verify the privacy masking with “user, id”.

Diversion: Verify the DID number.

Authorization: Verify the Digest Authentication implementation.

The following attributes in SIP message body are inspected using sniffer traces:

Connection Information (c line): Verify the IP addresses of near and far endpoints.

Time Description (t line): Verify the session timeout value of near and far endpoints.

Media Description (m line): Verify the audio port, codec, DTMF event description.

Media Attribute (a line): Verify the specific audio port, codec, ptime, send/ receive

abilities, DTMF event and fax attributes.

Use a network sniffing tool e.g. Wireshark to monitor the SIP signaling between the enterprise

and Bell Canada. The sniffer traces are captured at the public interface of BCM450.
