We are configuring voip for a remote worker that uses a Virgin CM and having some problems. She is in Leamington which from memory makes her ex-ntl (Langley)
Do you know if any of the following ports are restricted in any way on ntl?
IAX - 4569 UDP
SIP - 5060, 5061,5064,5065 tcp/UDP
RTP - 16384-16482 UDP
STUN - 8000-8006 TCP/UDP
Protocol 47GRE
Many thanks if you are able to answer this
Mark
