Debugging inbound call - need debug command

I am debugging what I believe to be a dial plan issue on PGW but want to run a debug command on the ITP to show the actual called number of the inbound call.

What is the best debug command to use to see the inbound called and calling numbers of a call.

You are better off capturing an mdl trace from the PGW using per call tracing or using snoop and opening the call in Wireshark.

The ITP will only dump hex values and you will need to decode them yourself since it is not concerned with ISUP layer. You can use the cs7 paklog feature to attach an access list to a linkset and then send the raw data to a syslog server for decoding.

For example:

cs7 paklog x.x.x.x dest-port xxxx src-port yyyy

access-list 2700 instance x permit si all

debug cs7 mtp3 paklog 2700
