Dear Maintainer,

   * What led up to the situation?

After installing the security fix in bullseye (16.16.1~dfsg-1+deb11u1 to
16.28.0~dfsg-0+deb11u1) calls with fail after 120 seconds with the
following error on the console:

res_pjsip_sdp_rtp.c:145 rtp_check_timeout: Disconnecting channel for lack of video RTP activity in 120 seconds

After downgrading back to 16.16 calls keep up longer then 2 minutes
again.

Hi,

I have found the reason for the disconnects.

I have set the pjsip rtp_timeout to 120 and after the update this
setting suddenly became active.

I futher investigated this issue and found the the default value for
this setting is 0 and I have changed the value now to 0 and the issue is
gone now.

Seems still that there is an issue with the rtp timeout, because I have
rtp traffice but it can be avoided with removing the setting.

Bug can be closed

thanks
Philipp
