No sound on outgoing calls - Acrobits

Hi,
I have a US flynumber and the Acrobits app.
Receiving calls is fine.
Calling US numbers from Acrobits is fine. (Outgoing calls are enabled in PBX.)
But if I try to call a UK number, it connects but I can’t hear anything and neither can the other person.

Any thoughts?

Thanks!

Can you try a different network location just in case, I would also try restarting the app

If that doesn’t do the trick please also try different codecs on the app. Give priority to G711 ULAW and/or ALAW. Try GSM as well.

Finally, make sure STUN and sRTP is off in the SIP app.

Worst case I would try a new set of SIP credentials from the PBX and enter into the app.

Please let us know if this persists as we can debug from here

Note: Another tip is to toggle the “transport” ( also a setting in all SIP clients ) from UDP to TCP or vice versa
