Answered Question
May 2nd, 2008

I am using an as5400 hpx as a sip gateway. I am establishing a pri to a Nortel DMS-10 pstn switch. I do not get

calling name deliveried to sip phones from the pstn. After debugging q931 messages I find that calling name is being provided in a Facility message.

I have this problem too.
