Router is 2821 with DMS-100 PRI in Canada (no TCAP DB here). I am receiving NOTIFYs with Connected Address & Display IE's from the switch. This info is relayed to the CUCM in MGCP mode but not in H.323. Is there a way to get Called ID updates on the endpoints other than using MGCP?
Example 1:
Two CUCM's in 2 different cities, both have DMS-100 PRI's on MGCP gateways.
From my IP phone on CUCM1 I call DID in CUCM2 via PSTN. This DID is the VM pilot number, which points to extension 4000 which is the internal VM pilot number. CUCM2 sends Connected Address (4000) & Display IE ("VoiceMail") in a NOTIFY message which gets relayed to CUCM1. Phone updates Called ID display to reflect the new Connected Address & Display IE. This is exactly how I want it to work - I know I should present E.164 numbers or at least 10-digit numbers but this is a failover scenario where we use the PSTN as a fallback in case the ICT's go down.
Example 2:
Two same CUCM's in 2 different cities, both have DMS-100 PRI's, CUCM1 is H.323 & CUCM2 is MGCP.
From my IP phone on CUCM 1 I call DID in CUCM2 via PSTN. CUCM2 sends Connected Address & Display IE in a NOTIFY message which gets relayed to PRI GW at CUCM1 site (shows up in deb isdn q931). This info doesn't make it to the CUCM, phone display does not change with revised Called ID.
I've tried using signaling forward unconditional under voice service voip & the like, to no avail. I know my PRI setup is good as we manage the "telco" side of things as well. Any ideas?
