[Freeswitch-users] Problem listening to PCMU and ul recordings

I've been using the record_session feature and wish to use PCMU or ul audio
format, but when I try to play back the audio in either format, it sounds
high-pitch and fast as if it is playing back at 2x speed. I looked at the
waveform recorded in PCMU and ul versus what it looks like when I record as
wav, and it seems like it is only recording every-other sample (which would
explain the pitch and speed).
My vars.xml is set to PCMU as the global codec pref and the outbound codec
I am recording in stereo (one channel per leg of the call), but I'm not
messing with any other recording parameters.
Incedentally, the wav sounds just fine, but I'd prefer an 8-bit mulaw audio
file, because I'm getting calls off a T1 (actually off of an AudioCodes
Mediant 1000 that is converting the T1 to SIP for me), and I'd like to
record precicely what is coming off the wire.
I'd be happy to send any configuration files, I'm just currently at a loss
for how to proceed.
