[SR-Users] How to handle SIP-I(ISUP) with Kamailio

[Waseem Zaidi]

Hi All:

I am new to the list, I am struggling to find out Kamailio's capabilities
with SIP-I/ISUP. I see that there is SIP-T module in kamailio and ss7ops
module, but I need to get a hold on how to start. I would appreciate if
someone could guide me.

previously, I tried to use OpenSIPS SIP-I to extract ISUP from incoming
calls, i was able to extract ISUP parameters in SDP body as

xlog("Called Number: $isup_param_str(Called Party Number|Address
signal)\r\n");
xlog("Calling Number: $isup_param_str(Calling Party Number|Address
signal)\r\n");
xlog("Location is: $isup_param_str(Location Number)\r\n");

Location parameter is appearing as 0x04971400330268 which is wrongly
interpreted. its proper interpretation should appear as 4100332086.

I also tried below:
xlog("Location is: $isup_param_str(Location Number|Address signal)\r\n");
but this subfield is not present.

The transformation didn't make any difference:
xlog("Location NUM: $(var(isup_body){isup.param, Location Number}

Help pleeez ?
