Bug#1024709: asterisk: Calls fail after 120 seconds with 'lack of video RTP activity in 120 seconds'

[Philipp Kolmann]

Package: asterisk
Version: 1:16.28.0~dfsg-0+deb11u1
Severity: important

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.
