I have clients who have existing Nortel PBX everywhere on their 24 spoke sites.
More info as follows:-
Functionaity - they only cares abt basic phone functions, and they want Voicemail
Seats - about 300 initially, but will grow to 1000 eventaully
Model of PBX - Nortel C1000
Network infrastructure - loads of HP switches (L2) with 1841
routers / 3620 L3 (10 mb) interfaces routers
Thanks for any help in advance.
