I am investigating a problem on the transfer and I am finally seeing the bottom of the tunnel …
In practice, after having solved several other problems, the transfer call “* 72” now appears to be taking place.
The audio does not pass the la chimate remains open 31 seconds
Going to the log here is what it looks like:
[2020-05-25 11:11:11] NOTICE [1883] chan_sip.c: Disconnecting call ‘SIP / 0108933606_out-00000075’ for lack of RTP activity in 31 seconds
[2020-05-25 11:11:11] NOTICE [1883] chan_sip.c: Disconnecting call ‘SIP / 0108933605_in-00000074’ for lack of RTP activity in 31 seconds
It would seem an RTP communication problem
The problem occurs both on a machine behind a draytek router with DMZ on the PBX and on a machine in the cloud when without any nat
Someone manages to give me an idea, thank you all for your collaboration
