I got this working properly. The basic problem was CIC lineup/mapping. Our
mux had the E1s mapped incorrectly. So what we thought was E1-1 was E1-5.
Thanks,
Dave

I wanted to add that I checked and my CICs are lined up correctly on both
sides. I am using Asterisk 1.6.2.13.

Hi Guys,
I am having a similar issue with no audio. Other end is an ericsson switch.
See the logs below. I can make and receive calls fine but no audio. I
checked my CIC and they are lined up well. I run dahdi_monitor but I only
see activity from my end (softphone registered on asterisk). Nothing from
the far end. One strange thing I notice is the # sign at the end of the
numbers in the logs.
