BCM 50 SITE-TO-SITE QUESTIONS ???

[dcommusa]

I have a customer that expanded to a new site & its time for a new system-I'm thinking BCM 50......However I have some questions!!!!Proposed parameters:
Main site= 12-T7316e,4-8 pots/analog trunks,12 v.m. seats
Remote site= 6-T7316e,4 pots/analog trunks,8 v.m. seats

The customer wants to be able to dial DN's from site-to-site & transfer in-bound calls back & forth.(They also want to external page back & forth)(main site is using cable for internet & remote=DSL)

Question's

1.Do I need mcdn/keycode to dial site-to site?
2.Do I need IP trunk keycodes for dialing site-to-site?
3.Does their IT person need to do vpn/firewall @ each site
for this config?
4.Would BCM 50 @ main site & IP phones @ remote be a better option?
5.If they get a call @ the main site & park it-can they pick it up @ the remote side?

Any suggestions/draw backs/ideas would be appreciated!!!!

THANK YOU

You also need to understand that if you use IP sets at the remote location, you will still need to have a PSTN on a phone at the remote site for 911 requirements.
