Howto:Xtratelecom - Trunk SIP - SIP Provider Compatibility Test
Innovaphone Compatibility Test Report
Summary
SIP Provider: Xtratelecom
The provider doesn't support Reverse Media negotiation, so media relay and an exclusive coder setting must be configured.
The provider supports redundancy. As long as the IP addresses of the PBXs are defined in the Xtratelecom side they can send and receive calls to/from any of them.
Fax is supported, but it needs an extra SIP trunk in the PBX side pointing to a different IP. Xtratelecom defines it as a service called 'Endpoint de fax' that needs to be purchased separately.
Current test state
This product is being tested right now. The test is not yet completed.
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.
