Hello,

I have freeswitch version 1.10.5 -release-17-25569c1631 64bit installed.

I have one SIP provider, no nat.

I use a simple dialplan which bridge the received call from SIP provider to a mobile number using the same provider.

The call goes through but I have no ringback tone and if I answer there is no audio.

If I send the call to one internal extension, it is working fine.

The only difference I can see in the logs is that, on the call with no audio, I do not have in logs „Correct ip/port confirmed”.

Any suggestion is greatly appreciated.

Thank you.

Best regards,

Mircea.
