There is a Cisco Router between my pabx and the VOIP provider. The VOIP provider assures me they are listening on all RTP ports and the company who set up the cisco router assures me that they are allowing all RTP traffic. I have supplied them with a list of all Ports used according to TC1235.
I know it has to be RTP ports somewhere. From what I could read on another traces the traffic was on udp ports 32514,32515,57348,57349 and 32696 but they say they are allowing all rtp traffic.
I know its not the pabx as I have another SIP account to different provider that works fine but I am struggling to prove to them they are at Fault.
I have other traces as well if that would help?
