I've re-tested using version 1.10.1, FreeSWITCH still generates RTP packets to fill in the gaps when there's missed RTP packets, but the RTP timestamps are now correct which resolves the issue. I'll raise the issue on GitHub, as this appears to be a bug. ________________________________ From: FreeSWITCH-users <freeswitch-users-bounces@lists.freeswitch.org> on behalf of Shaun Stokes <shaun@sysconfig.cloud> Sent: 09 July 2022 13:18 To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Subject: [Freeswitch-users] Recording calls causes FS generated RTP packets with different timestamp on missed packets 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.

Thanks, Shaun
