My company is looking at some options to move to a converged architecture, and I would love some opinions. We have contracted a consultant, but I am trying to keep up with my own research as well.

Current systems:
Merlin Magix R2.0
Merlin Messaging
8 analog trunks
30 digital extensions

Partner ACS R6.0
Partner Messaging
5 analog trunks
10 digital extensions

6000/768 ADSL service

Main goals:
Trunk the 2 locations together onto the same dial plan and voicemail.
Converge data and voice service to lower cost.
Integrate with existing handsets (Lucent 4400, Partner 18).
Open upgrade path (SIP, H.323).
Meet these goals as economically as possible!

What are some of your preferred solutions to this problem? Voice capacities are not expected to grow much from our current specs. I am vendor neutral, so anything goes. wink
