Testing Enviroment

This scenario describes a setup where the PBX and phones are in a private network.

There are 3 major configuration variants of the SIP trunk, which one is used depends on the test results. The variants are:

• the SIP trunk is configured without Media Relay and without exclusive coder. This is the case if all tests were successful
• the SIP trunk is configured with Media Relay and STUN but without exclusive coder. This is the case when the test for "NAT Traversal" fails
• the SIP trunk is configured with Media Relay and exclusive coder. This is the case when the test for "Reverse Media Negotiation" fails

The test scenario should describe which SIP trunk configuration is needed.

In this scenario, I didn't had the change to test with a Fax, as no fax is currently available. As described in the test, it is possible to ask this as well at the Provider. He assured me that T38 protocol and the Transcoding of this protocol are not a problem.

Test Results

For more information on the test procedure, please read the following wiki article: SIP Interop Test Description. Bold lines in the test results indicate a KO-criteria.

FIXME: Note: Possible test results are Ok, Nok, Not tested, N/A(not available). Ok, Nok, N/A are self explanatory. "Not tested" is more a temporary note - if its still in the test after finishing, then the summary should explain why the feature was not tested. Remove this note in the final report
