SS7BOX Line Debugging
Symptoms: Outgoing IAM messages are not acked by the telco.
Outgoing calls do not work - no ring audio at all.
Solution: ISUP NI value is mis-configured
Change directory to /usr/local/ss7box
--> cd /usr/local/ss7box
Start ss7boxd with showmsu option
--> ./ss7boxd --showmsu
--> All the ss7 MSUs will be logged into /usr/local/ss7box/msu.log
Start ss7boost and enable ss7boost logging
-->./ss7boost
-> ./ss7boost_cli --log-verbose on 1
Then watch for block and block ack in /var/log/messages
Telco said we were not sending block ack when i saw them in log i wen to /ss7box/msu.log
Look for for message hex 13 and hex 15 for CIC 1 that is when i saw the NI value was different.
NI is set for ISPU messages in the TRUNK_GROUPS section of /etc/ss7box/ss7boost.conf
The telco was unable or uncooperative about having switch work with a single channel it was bouncing 61 channels all at once and telco just said we were not sending block ack what really happens is switch tosses out our block ack because it did not pass the NI filter and telco is not able to tell about that problem - switch does not announce it, or switch techs don't know how to look for it
when finished, restart ss7box without the --showmsu and turn of verbose logging ./ss7boost_cli --log-verbose off
