Hi,
I am using 3cx version 18 (update 6) on Debian 10 and it is hosted in our data center.
The network setup is
3cx Mobile App -> 3CX PBX -> Voip Gateway -> Analog Phone Line -> fixed line phone
The Voip Gateway is registered to 3CX PBX.as a SIP Trunk (Analog).
A call is made from 3CX Mobile App to a Fixed line phone number.
From the wireshark capture from 3CX PBX, the INVITE was sent to Voip Gateway. The VoIP Gateway responded with 100 Trying and 200 OK.
However, 3CX PBX did not respond with ACK after it receives 200 OK. The call is then disconnected after 1 min due to 3CX PBX did not send the ACK
Can any one advise why 3CX PBX did not respond with ACK for the 200 OK ?
Thanks.
Regards,
Kwang Mien
