[asterisk-ss7] Help with SS7 (No Audio)

[dave george]

Hi Tim,

Make sure your CICs line up.  Check that your T1-1 is the other side T1-1.
I had a similar problem and my CIC was not lined up.  My T1-1 was their
T1-5.


Thanks,
Dave

Thank you Gentlemen for your responses.

I have done the dahdi_monitor, its only TX that has some input (see
sample output below). Thats for both outgoing and incoming calls.

How can I verify the circuit mapping? My core engineer (telco company)
said that he is using the 1st channel for signalling and the rest for
voice.

I appreciate your help.

Tim
