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

[Abdul Basit]

Try sending a call via call file and see if you are getting both call legs.

callchannel.sh

#!/bin/bash
echo "Channel: DAHDI/$1/$2
Callerid: $2
MaxRetries: 2
RetryTime: 60
WaitTime: 30
Context: ss7
Application: Echo" > /var/spool/asterisk/tmp/test.call

mv /var/spool/asterisk/tmp/test.call /var/spool/asterisk/outgoing

dahdi_monitor $1 -vv

This is the way i verify the call legs.

chmod +x callchannel.sh

./callchannel.sh channelNumber someNumber
./callchannel.sh 3 123456789


Most of the time problem is cic miss-match.
I hope this will help you debugging the issue.
