Re: [Linphone-users] Incoming videocalls in linphone-android-5.0.8.apk are hung up after about 32 seconds by linphone app

[Sylvain Berfini]

Hi Antonio,

The difference between the two is that in the case that doesn't work, the ACK for the 200 OK isn't being received by the app:

2023-04-04 22:24:01:528 [org.linphone/belle-sip] ERROR Dialog [0x7144011f00] was not ACK'd within T1*64 seconds.
2023-04-04 22:24:01:529 [org.linphone/belle-sip] ERROR Dialog [0x7144011f00] it is going to be terminated automatically.

This is due to a packet loss, quite common when using UDP (which we don't recommend).
Why it happens in 5.0 release and not in 4.6, it may simply be because the 200 OK is a bit bigger in 5.0 due to RTCP info, and that may be enough for it to get lost.

Best regards,

Sylvain Berfini

Dear Linphone Development Team,

The logs file "v5.0.8_videocall_incoming_nok_32sg_hangup.gz" obtained from

linphone-android-5.0.8.apk (2023-03-20 09:47) currently available on Google Play are attached, 

where 32 seconds after the video call was picked up, the hangup occurs. The caller hangs up at 0 seconds.

There are also attached a logs file "v4.6.14_videocall_incoming_67sg OK.gz" from linphone-android-4.6.14.apk (2022-09-20 09:09) 

of an incoming video call made on the same device and conditions as the previous one, 

where the video call works perfectly beyond 65 seconds when an intentional hangup occurs.

Best regards,

Thanks,

Antonio.
