[Freeswitch-users] IVR codec issue (I think)

HI Everybody! I had a recent problem where a transferred call's audio was highly degraded. The cause was identified as mismatched codecs - thanks again. Today, I have a VERY VERY similar problem. The difference is that the first step is an IVR, not the receptionist. How do I set the CODEC for an incoming call to 711u when it is routed to an IVR. Thanks, Sean
