To the best of my knowledge, using Monitor, MixMonitor, or enabling
OTR (using "W" or "w" on the DIal command), automatically implies
"canreinvite=no" for the duration of that call. It certainly works
that way here at the moment. "canreinvite=no" would also only apply
for SIP to SIP calls.

We are recording SIP and Zap calls using Monitor here with no special
treatment for different channels - As far as I know, the recording is
done in Asterisk-core, and not by the channel itself.

Perhaps the OP could give an example of the dialplan which fails to
record a SIP conversation? What happens for SIP to Zap or Zap to SIP
calls? Does anything at-all get recorded? Is it zero-length, or
silent?

Regards,
Steve
