A little information about Acme, personal opinion:<br><br>Acme has a large SP market share because they were there first, and it took Cisco a while to release an SBC that had similar scalability. The ASR platform opened up a large part of the space where Acme had been before, so it's worth taking a look if you're looking at 2500+ sessions. I haven't had much experience with Acme except dealing with some interop issues, so I'll leave that to people that have had experience.<br>
<br>I don't know of any specific reference architectures for SP Voice. This is the design bible for voice, but it's more enterprise-centric: <a href="http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/uc8x.html">http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/uc8x.html</a><br>

Not talking about books here but my understanding is that Acme Packet makes<br>
service provider-level B2BUAs that are top of the market...not cheap but durable<br>
<br>
and used by many of the very large Telcos out there including British Telecom.<br>

Subject: [cisco-voip] cisco itsp architecture & books?<br>
<div><div></div><div class="h5"><br>
Everyone,<br>
We currently operate a ITSP and it has become my task to seek out replacements<br>
for our existing SIP platform (since we have some cash flow!); we currently use<br>
opensips, opensbc, metaswitch, and hundreds of cisco IAD2431s. We use the IAD &<br>
custom-sip everything to be able to offer modem/fax/theworks over IP, and it<br>
works flawlessly and allows us to compete on SMBs who require alarm systems,<br>
credit card machines, faxing, etc as a drop-in replacement.<br>
<br>
That said, we've run into some limitations with our platform, and I am exploring<br>
<br>
going all Cisco (which is what I'm most comfortable with as a network engineer).<br>
<br>
Can you guys point me towards some provider-style architecture or designs using<br>
Cisco kit? Links to presentations are especially helpful, or some<br>
recommendations on Cisco VoIP Provider books would be fantastic.<br>
<br>
Thanks -<br>
Randal<br>
