Hi
Does anyone have the same problem, or know the solution?
Multiple warning messages on Asterisk 1.4.36: Dropping incompatible
voice frame on Local/….
when receiving calls with codec A and doing multiple attended
transfers to codec B
Reproduced with the following channel combinations
SIP -> SIP -> SIP…
IAX -> SIP -> SIP…
DAHDI -> SIP -> SIP..
Tested in different systems that I’ve upgraded from 1.4.22 to 1.4.36,
tested with different codecs.
g729 -> alaw
ilbc -> alaw
alaw -> ilbc
alaw -> g729
…
Tried to set transcode_via_sln=no and restarting *, it has no effect.
moh files in wav format, also tried moh files in multiple formats to
avoid transcoding..

I have about 7K to 10K of this warning messages per day in all my
systems with 1.4.36 version.
