Testing of this product has been finalized February 22th, 2016.
Tests with MediaRelay
- Registration
- The provider supports UDP and TCP as transport protocol. The tests were completed using TCP, since UDP is an unreliable protocol and requires all involved network elements to support IP-fragmentation.
- CLIP
- OK
- CLIR
- OK
- CLNS
- OK. Redirection based on the Diversion number or based on "302 Moved Temporary" is not possible. Since CLNS is possible, it has no effect on forwarded or Mobility calls.
- codecs
- G711A, G711U, G729A, G722, OPUS.
- Fax
- Transport of faxes to/from the PSTN via G.711A codec was tested successfully. Additionally transport of faxes to/from the PSTN using the T.38 protocol was tested successfully. This is important for the innovaphone Fax-server. Even if the provider supports T.38, it is not guaranteed that all Fax-calls use T.38. However each call using T.38 will save you 2 DSP-licenses on the gateway hosting the Fax-interface.
- SRTP
- The provider supports audio encryption using SRTP for incoming, outgoing, intern calls.
- DTMF (RFC2833)
- OK
- NAT Traversal
- The provider detects clients behind NAT and can handle calls to them without requiring the clients to use NAT-traversal methods like STUN.
- Reverse Media Negotiation
- OK
- Mobility Call
- OK
- Redundancy
- OK
- IP-Fragmentation
- OK
- Large SIP messages
- OK
- Correct signalling of Ringing-state
- OK
- Early-Media
- OK
- Session Timer
- OK
- Call Transfer
- OK

The test results without MediaRelay are equal to the ones with MediaRelay.
