Hello. I’m trying to do a call between 2 soft phones - 101 (192.168.168.106 - marti) and 100 (192.168.168.104 - stan).
In order to get the NAT out of the equation, the calls are done locally. The asterisk IP is 192.168.169.20. The hostname is replaced with MY_ASTERISK_DOMAIN.
I’m able to hear both directions just fine, but after 31-32 seconds the call just drops. Complete SIP trace of the communications can be seen here
The system is behaving as though the ACK is never reaching UDP:192.168.168.106:45313 or is not being recognised when it reaches there. You need to find out if the ACK is reaching its destination and if it is, look at logs from the destination to work out why it is being ignored…
Well, according to wireshark seems that the ACK is going to the mobile phone, and the OK is coming from the same port the ACK is supposed to arrive. Linphone on android is used on both ends if that matters. What can the reason be in that case?
@david551@jcolp thank you guys! With the asterisk aside, I tried many settings on the linphone side, and turned out that setting the server address at the “Outbound proxy” as well fixed the issue. No more 200 OK’s - only ACKs and the call isn’t dropping like earlier.
