[Freeswitch-users] Recording calls causes FS generated RTP packets with different timestamp on missed packets

[Shaun Stokes]

Hi All,

We're having issues when recording calls, using either record_session or uuid_record.  FreeSWITCH is generating RTP packets to fill in the gaps when there's missed RTP packets (packet loss), but the FreeSWITCH generated RTP packets use a different timestamp. This causes jitter and periods of silence on active calls. The only solution seems to be enabling RTP rewrite timestamps, but this causes audio delay\sync issues.

We've tried with and with-out the following, but there's no change.

  *   bridge_generate_comfort_noise
  *   send_silence_when_idle
  *   suppress_cng
  *   suppress-cng (SIP profile param)

Has anyone come across this before, and is there a solution?

Thanks,
Shaun
