[Linphone-users] No sound either way on calls

[Znoteer]

Hello,

I tried using LinPhone on my Android device to make calls through a voip
provider.  I tried to call two different people, using each of UDP, TCP and
TLS.  In all cases, when the call was answered by the remote party, nothing
could be heard by either of us.  The only difference between the two calls
was that I could hear the remote phone ringing in my earpiece for one of the
numbers, but not for the other.

The technician with my Voip provider also had me try to connect over both
WiFi and mobile data.  There was no difference.  

The next thing the technician suggested was to try a different VOIP/SIP
application.  I tried GSWave.  The calls worked immediately.  Aside from
occasional echo, the sound was very good on both ends.

I'd rather use Linphone.  My Voip provider is not willing to help debug this
any further.  Do you have any ideas why there isn't any sound when calling
with Linphone?  Anyone willing to help debug?

Thanks,
