Recently i am helping customer intergrate BT - Brokerage phone system with Cisco voice gateway via qsig. My customer using Call manager 7.1 and unityconnection 2.x. Call function between BT phone system with call manager via qsig working fine however only extension number show on BT and cisco phone.
How to allow both phone system show caller name?
Hi, what I can see is that the BT side sends Daniel Cheney as the name.
Call from BT to Cisco: Contained in Setup
Call from Cisco to BT: Contained in Connect
To get the Cisco side to send the information you have to check if an alerting name is configured on the phones line and if you filter somewhere this information out. Same for the other direction BT is sending the information, check for any accidently active filters.
Ok, I just saw that you are using H323. MGCP is best for that scenario (my experience).
Anyway you could try this with h323:
voice service voip
h225 display-ie ccm-compatible
dial peer to cucm
h225 display-ie ccm-compatible system
isdn supp-service name calling
