[Asterisk-biz] SIP Origination and Termination w/ 200K Minutes

[Max Clark]

Hi all,

I am currently performing a feasibility study to convert a ~1200 station 
enterprise from an ageing TDM PBX to a new VoIP PBX. I have two questions:

1. How many minutes/month should I be expecting with this type of system 
(ballpark average)? I have heard everything from ten minutes per day per 
station (360,000) to 1/3 of total stations x 10,000 minutes (3.6 million).

2. If I implement this using TDM T1's for the inbound and local calling 
I am expecting to significantly reduce the total number of minutes. 
Assuming 1/2 of the low end (180,000 minutes) I am underneath the 1/4 
million minutes that most carriers seem to want for SIP-SIP 
connectivity. Are there any carriers in Los Angeles that will provide 
SIP-SIP connectivity for this quantity commitment? What kind of pricing 
am I looking at?

Thanks in advance,
Max
