I have a customer who have (2) Nortel Meridian 81 and (1) CS1000 for their 3 locations along with Octal 350 servicing 2500 voicemail users today. Customer also has a Cisco UCM in their network today which is servicing their wireless phone users.
UCM and CS1000 are networked together using Q.Sig trunks today. Customer is looking at replacing their Octal solution with a new Voice mail solution.
I was looking at integration documents for Unity Connection using PIMG.
In this scenario, would I need 3 separate PIMG 's at the three remote sites and integrate it with Unity connection or Can I achieve this using just one PIMG at one of the sites, considering the three sites are trunked together using tie-trunks.
Appreciate any pointers/ help.
