I have a newly installed sipxecs 4.2 system (replaced a previously installed v3.10 system). System is behind a NAT firewall. All works as expected (internal extension to extension calls, outbound calls, inbound calls, etc). I have also followed the v4.2 remote worker config guide and configured the server accordingly (port forwarding, local subnet specified, etc).
I have installed Acrobits SIP client on an iPhone and configured it as an extension in sipxecs. Using the local WiFi network, the iPhone SIP client registers and can call/communicate with any extension as expected. Using 3G, the Acrobits SIP client registers properly and can call internal extensions, but the media streams (RTP) are never established. I have captured the net traffic at the server in the failure case and it appears that the RTP traffic inbound from the (remote) iPhone is arriving at the sipxecs server and is being properly sent on to the internal extension. However, I don't see any RTP traffic heading outbound to the iPhone. I think this is the problem... Does anyone have recommendations for further diagnosing this scenario? I can post a wireshark capture of the traffic in the failure case...if that's helpful.
