We are planning to enable URI dialing and I found following information in Support Forum:
There is a taks when I have to enable "Use Fully Qualified Domain Name in SIP Requests"
What does this exactly mean ? Do I have to reset something or restart ? Could I get trouble or do the system just add FQDN to SIP Messages ?
Thanks in advanced.
Solved! Go to Solution.
This feature enables CUCM to send an alphanumeric hostname of the calling party through to the called endpoint as a part of the SIP header information. This enables the called endpoint to return the call using the received or missed call list. If the call is originated from a phone and is being routed on a SIP trunk then the configured Organizational Top-Level Domain (e.g., bell.ca.com) will be used in the Identity headers, such as From, Remote-Party-ID, and P-Asserted-ID.
For example, in this cluster the OTLD is set to bell.ca.com. The SIP request from a phone on this cluster will look like this.
INVITE sip:+email@example.com:5060 SIP/2.0
From: "Denva Brooks" <sip:+firstname.lastname@example.org>;tag=10798617~76174c53-
P-Asserted-Identity: "Denva Brooks" <sip:+email@example.com>
Remote-Party-ID: "Denva Brooks" <sip:+firstname.lastname@example.org>;party=calling;screen=yes;privacy=off
NB: That the From, PAI and RPID headers all have alphanumeric values and the host portion of these headers is the value set in the OTLD.
Thanks for answer.
Is it a must to enable "Use Fully Qualified Domain Name in SIP Requests" for URI dialing ?
Ok thanks. I will try on weekend on my change window. I will enable the sync E-Mail to URI of enduser and in Jabber it is already enable.
I will keep this post updated...
