[cisco-voip] SIP Trunk Provider PRI Handoff or CUBE?

[Ted Nugent]

I received a call from a former client (I switched partners) that is
migrating sites over from PRI to SIP and has an arrangement with his
provider that they will provide PRI handoffs via Adtran gateways so that he
does not need to purchase additional hardware or licencing. Apparently, His
Cisco account team caught wind of this and told him this was against "Cisco
Best Practice", that he will experience nothing but problems and needs to
have CUBE in place and take SIP directly to CUBE, then proceeded to quote
him $50k in upgraded routers and licensing.... This is where I got called
and figured before I start up the bus and start tossing people under it I
would ask you folks to see if there was anything I might be missing
here? Using the PRI handofffs sound reasonable to me since there does not
seem to be any compelling reason I can think of to go to CUBE in his
situation.
I've seen many clients running SIP trunks with PRI handoffs for the same
reasons and to my knowledge have had zero problems.... It sounds to me like
it's Cisco's Year End and someone is embellishing the truth to sell
unnecessary gear.... Anyone else know of any issues of terminating the SIP
trunk on an Adtran and providing a PRI handoff, assuming you don't need
more than the 23 channels....?
