[Freeswitch-users] Garbled Leg Recording G729 with Asynchronous ptime

Please, I was wondering if there is anything obvious that we are missing
when trying to record a G729 call with asynchronous pimes (in: 20ms, out:

The problem case call flow is:  inbound leg (ptime 20 ms), start recording,
playback a short message, bridge to outbound (destination can only handle a
ptime of 60 ms).   We are using mod_com_g729's codec.   The audio while on
the call in normally fine (rarely there is one way speech depending on
inbound/outbound provider), but *the recording has a garbled outbound
(Callee) leg* (inbound/Caller voice is fine.).

We have tried all the combinations of  G729 at 20i, G729 at 60i,
rtp-autofix-timing, and default-ptimes to no avail.

We are using git HEAD.

I do see this on fs_cli:

Should this be working, are we missing something obvious?

Thank you,

Kind regards,
