[Freeswitch-users] Fax Codecs

[Joseph L. Casale]

While faxing is working, I am seeing these in the log when I
attempt to use rxfax:

switch_ivr_play_say.c:1154 Codec Activated L16 at 8000hz 1 channels 30ms
switch_core_io.c:652 sofia/internal/1002 at 192.168.13.1 receive message [TRANSCODING_NECESSARY]

So later I see:
switch_core_codec.c:128 sofia/internal/1002 at 192.168.13.1 Restore previous codec PCMU:0

So I am actually not clear on what's happening? I thought I had the ua set to PCMU but I
guess fs is seeing the incoming sip session as L16 which I read is bad for fax? What's
the significance of the last line where it states its restoring the old codec?

Can anyone shed some light on what's actually happening?

Thanks!
