Innovaphone Compatibility Test Report

Summary

SIP Provider: swisscom

The provider supports all mandatory innovaphone features and is therefore qualified as recommended SIP Provider.

That being said, the provider has achieved 86,34% of all possible test points (139 of 161). For more information on the test rating, please refer to Test Description V11 and later


Please Note, that some features are restricted or not supported by swisscom

  • Fax over IP (T.38) is not supported
  • Only G.711a is supported, no other codecs are supported
  • Overlapped Sending is not supported
  • NAT Detection is not supported
  • Redundancy Mechanism are not supported
  • SIP over TCP is not supported
  • Incoming Early Media Channel is not supported by default and must be requestet to swisscom.
  • Fax via G.711 (T.38 to G.711) is not supported by swisscom but should work in most scenarios. This Feature is not guaranteed!
  • CLIP no screening does not work for "Trunk loop Connections". This means, if you dial out to the PSTN and back to your own Trunk Number, CLNS does not work.


Since the provider doesn't support Reverse Media negotiation, media relay and an exclusive coder setting must be configured. Opposed to a SIP trunk not needing Media-Relay, the transport of all RTP packets by the gateway will result in a higher CPU load for a call. As a result, the amount of concurrent calls is considerably lower compared to a SIP-Provider that doesn't require Media-Relay.

In order to use some Features like Clip no screening, some configuration must be done.

Supported Features:

  • Direct Dial In
  • DTMF
  • CGPN can be suppressed
  • CLIP No Screening
  • Reverse Media Negotiation
  • Hold/Retrieve
  • Blind Transfer

Supported Codecs:

  • G.711a only

Current test state

This product is being tested right now. The test is not yet completed.


Testing Enviroment

SIPProviderTestTopology1.PNG

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

The swisscom is providing an own Gateway ("Patton Smart Node") which must be located in the customers private network. This Gateway has two connections:

  • One connection to swisscom
  • One connection to the PBX

Because of this, the SIP Trunk does not connect directly to the internet, but to the swisscom Gateway ("Patton Smart Node").

The SIP trunk must be configured with "Media Relay", "exclusive G.711a" and "NO T.38".

Test Results

For more information on the test procedure, please read the following wiki article: Test Description V11 and later. Bold lines in the test results indicate a KO-criteria.
