Summary

SIP Provider: Winitu

The provider does not support all required innovaphone features.
However, this provider has achieved 79% of all possible test points and some remarks have to be made.

Winitu:

  • G711U is not supported offnet(calls to PSTN) since within Europe this is not a custom codec. Onnet(calls within provider network) Winitu is codec independent, User Agents are free to use any available codec.
  • Winitu does not provide an early media message like This number is incomplete. Instead it provides a 404 error code when a dialled number is incomplete.

Supported Codecs by the provider:

  • G711A
  • G729
  • T.38


Features:

  • Direct Dial In
  • Fax over IP (T.38) (NOT TESTED!)
  • DTMF
  • NAT Detection (NOT TESTED!)
  • Hold/Retrieve
  • Transfer with-and without consultation
  • Blind Transfer
  • Broadcast Group & Waiting Queue

Testing Environment

Scenario NAT

Image:HFO_SIP_Compatibility_Test_5.PNG

This scenario describes a setup where the PBX and phones are in a private network. The IP800 must use a stun server, in order to send correct SIP - messages. The IP800 works as media relay, all RTP - streams go through the PBX.
