Dears
Thank you very much Anders for your prompt response I have tried the
suggested on and got the following output below but the problem is still the
same. See below the CLI out put and configuration for your reference.
One thing that I would like to ask you, is their any mean where I can get
the value of DNI? Or anything where I can store the value of DNI?
As far as I know we got the value on DNID in PRI where we can distinguish
between the calls but in ISUP the information I can see on CLI is DNI value.
See below the suggested with respective CLI output.
When I defined an extension for the dialing code 6789 in SS7 context. It
gave the below output on CLI
