Names not displayed on user phones

[greg.huber]

My VoIP implementation does not display the name of the calling party. The number is displayed, however, the name says "From Unknown Caller". I have validated with the carrier that our PRI circuits are configured to send through this information. How do I configure the gateway so that this information is displayed on the phones. I am running CallManager 4.1.

Can you try turning on debu isdn q931 and see if what exactly carrier is sending.

Also, what gateway protocol are you using

[greg.huber]

Gateway protocol is MGCP. here's some of the debug isdn q931:

Can you try selecting "Send Calling Name in Facility IE". Under your PRI configuration settings under Gateway.

PS: You have to reset your gateway to take these changes. Please plan accordingly

HTH

[greg.huber]

thank you very much for the info. I made the change and reset the gateway, however I still can't see the calling party name. I get the number but not the name. Any thoughts on what else could be the issue?
