[Freeswitch-users] Exchange 2007 UM - DTMF problem

[Anthony Minessale]

you can see in the trace that the exchange is using alaw.
So the complaint about trans coding is because it's going from PCMU on leg a
to PCMA when talking to exchange.


please revert any changes, upgrade to current SVN trunk and try configuring
exchange to use PCMA
or confiigure FS to only use PCMA by editing vars.xml and making the
codec_string be PMCA instead of PCMU
