Everyone,<br>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.<br>
<br>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.<br>
<br>Thanks -<br>Randal<br>
