passing caller Namer between CallManager & Lucent Difinity PBX

[moabdallah]

15 Site using 15 Definity Lucent PBX, connection between these PBXs is via PSTN network

A user from one site call a user from another site, the caller name appear on the handset of the called user

I am going to replace the HQ PBX with Cisco IP Telephony Cluster of three 7835 CallManager

Can I acheive this caller name feature with Cisco CallManger

I mean, Lucent digital phone from the remote site ( Lucent PBX ) call IP phone on the HQ ( cisco Callmanager 3.3(4) ) and the caller name appear on the ip phone on the HQ

IP phone from HQ ( Cisco CallManager ) can call Lucent digital phone on remote sites ( Lucent Difinity PBX ), and the caller name appear on the Lucent phone on the remote site

Calls between site are via PSTN ( E1 lines )

Is this possible ?

THe most straight forward way to do this is with ISDN.

ISDN will pass the phone number

Does it pass the caller name also ?
