Hi,
I can make and receive calls to and from my Iphone client (IOS9.1), however, when I make a call from the client no audio can be heard either way, but when I make a call to the client audio can be heard.
I've done a SIP trace and analysed it in Wireshark and audio is sent.
Also in the 'Stats' on the client during a call, the packets received stays at zero but the sent packets ticks over.
I've tried this over both Wifi and 3G/4G in case it was a NAT/ routing issue (my provider doesn't block SIP traffic).
Why do I only hear audio when making calls to the Iphoe client and not from it???
Any help would be great.
Cheers,
Carl
