This is my setup:
Kamailio -> FreeSWITCH (for voicemail)
...SIP gateway for connecting GSM
So every call is routed directly via Kamailio - between SIP clients and
in/out from the GSM space.
Testing with a cellular phone as one client and X-Lite on Mac OS X as the
other - everything works.
Testing with a cellular phone as one client and Bria on iOS as the other -
everything works except there's no sounds coming into Bria. The person on
the cellular can hear everything (sound coming from Bria), but Bria client
cannot hear sound from cellular phone.
Is it something to do with codec or could it be something else?
