Issue: Can get Ipod Touch to Ring and click on Answer, but no notification is sent to the calling device (cell phone or landline) that the call has been answered....and no voice transmit. The same iPod Touch can make calls via a TerraSip account and all is perfect. I am using a Touchmods mic and SipVoip 1.2 on a jailbroken Touch 1.1.4. The TerraSip folks suggested a possible firewall setting but I am not sure. Has anyone overcome a receive call issue where they get a ringtone and a prompt to answer, yet there is no communication on answer back to the calling phone?...it sounds like a last mile issue. I have debug logs of the SIP connection if it helps. Any and all help is appreciated.
