I'm pretty new to cisco, and am trying to configure a vic-2fxo-m3 in a nm-2v, on a 2621xm router.
I've got it working so that incoming calls on the fxo will ring my cisco phones, but when i answer and start talking, the speech on the cisco phone is really slow, and the speech on the calling phone is really fast (sounds like a chipmunk). Has anyone seen this before, and know where i should start looking?
My voice-port config is as follows -
supervisory disconnect dualtone mid-call
no echo-cancel enable
timeouts call-disconnect 3
timeouts wait-release 3
connection plar opx 101
