Re: Zahid’s post, I would assume Warren was referring the channelized robbed-bit T1 w/ 24 channels (I think the E1 is 30).
My understanding is that the PRI allows for a great degree of integration into a software solution (screen pops based on ANI/Caller ID) whereas a standard Robbed Bit T1 will not support those functions quite so readily.
I, too, am researching T1 vs. PRI feasibility for a 100 seat inbound call center. The prospective client has purchased two DS-3s (switch diversity) with standard T1s.
I am investigating ditching the DS3s and going to an individual PRI (or 6-8 PRIs) solution; I am unsure if the existing T1 circuits on the DS3 could be ‘converted’ to PRI or if that level of service would require different provisioning at the DS3 level. Any advice would be greatly appreciated.
