AS5400 cnam delivery to sip phones

[mike-singleton]

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.

Hi Mike,

Try configuring Buffered Calling-Name completion feature at the following url:

This allows the invite to be delayed by specified buffer-invite timer in order to await facility message with calling name information.
