[cisco-voip] cisco itsp architecture & books?

[Paul]

Not talking about books here but my understanding is that Acme Packet makes 
service provider-level B2BUAs that are top of the market...not cheap but durable 

and used by many of the very large Telcos out there including British Telecom.

Everyone,
We currently operate a ITSP and it has become my task to seek out replacements 
for our existing SIP platform (since we have some cash flow!); we currently use 
opensips, opensbc, metaswitch, and hundreds of cisco IAD2431s. We use the IAD & 
custom-sip everything to be able to offer modem/fax/theworks over IP, and it 
works flawlessly and allows us to compete on SMBs who require alarm systems, 
credit card machines, faxing, etc as a drop-in replacement.

That said, we've run into some limitations with our platform, and I am exploring 

going all Cisco (which is what I'm most comfortable with as a network engineer). 

Can you guys point me towards some provider-style architecture or designs using 
Cisco kit? Links to presentations are especially helpful, or some 
recommendations on Cisco VoIP Provider books would be fantastic.

Thanks -
Randal
