The SIP trunking is outstanding.....the fact that the SIP provider and ESI both have certified / approved each other makes it the clinching factor for me.....they won't point the finger at each other and leave the customer twisting in the wind.

The customer will now be able to finance a brand new phone system that will benefit from all of the features of SIP trunking as well as all of the new features for less than what i will be able to save them on ther bill so they get a new system with enhanced capabilities and thier monthly bill goes down...sounds like a win - win situation to me.

I called 3 long time customers of mine yesterday....i have 3 appointments....i like those numbers!!
