Caller ID - SIP call to E1/PRI (Q931) - p-preferred-id
I have a c2800 router running 12.4(13r)T IOS. This router has E1/PRI interfaces and is used as a gateway between a SIP network and the PSTN.
I have a SIP user who is sending his Caller ID using RFC3325. The Caller ID is not being sent to the PSTN. I think the Cisco router is using the description ("MyName") rather than the number ("8543210") and as this is an alphanumeric field this is not valid on the PSTN.

I was suggesting that a TCL script should be able to access any SIP header to set any parameter in the call. The example script posted the thread could not successfully access the sip headers, still I think once you can access them, a script would work.

If you want to download them you have to prefix "file get " and you can add one of the options (re...
