[asterisk-ss7] No Audio on SS7 calls to Remote PRIs

[dave george]

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.

 

Thanks,

Dave

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.

Example Address signals: 5339427#

 

 

libss7 version: 1.0.2

DAHDI Version: 2.4.0 Echo Canceller: MG2
