I am trying to ballpark a scenario for work where we are replacing copper telephone hybrids in 25 radio studios. The standing order right now is to provision 8 PRI lines and bring them in that way, but the system is/was built to fully accommodate SIP from end to end, and I'd like to show them that they can maybe save some ducats (and give me some flexibility) by adding SIP from a major provider.
Being a Federal agency, I still have to tiptoe through the FISMA regs and I know there are GSA contracts available for providers, but I'm just trying to get a ballpark figure to show them/compare those costs versus straight PRI (which will likely be $7200/month for all 8 PRIs under contract).
My requirement is for 100 separate DIDs, 650 simultaneous SIP registrations, a likely simultaneous SIP/RTP bandwidth of 15 Mb/sec (based on a G.711 codec).
Has anybody dealt with Windstream, Level3, AT&T, Peerless, etc. for this kind of capacity, plus a 100 Mb Metro-E connection to a local POP? Could I say with reasonable in-certainty that this would cost less?
With PRIs I am likely locked down to a G.711 codec. I'd like to show them with only a handful of calls to mobile providers that they calls can sound good again. BTW, 99% of these calls are going internationally (Africa, Southwest Asia).
Thanks for the opinions.
Carl
