Summary

SIP Provider: Winitu

The provider does not support all required innovaphone features.
However, this provider has achieved 83% of all possible test points and some remarks have to be made.

Testing Enviroment

Scenario NAT

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.
