<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Matt,<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks for the information. If you don't mind answering: are you guys developing this solution for your internal needs (meaning serving UAs from within your enterprise) or are you planning on offering services to the public?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>It's not that I'm really interested in your business or business model. I'm mainly curious to know how you will deal with potential UAs that are behind external NATs. Will you Asterisk "farm" stand behind a NAT or will it all be "publicly" accessible where no NAT translation or port forwarding will exist? I read the section on Asterisk and NAT on the wiki but still left me with some open questions.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>In my particular setup, I work in a small call center. I have Asterisk behind one NAT with port forwarding on port 5060 and ports 10000-20000, only because I have 2 remote agents. The rest of the agents are in-house. The remote agents themselves are behind other NATs (behind their DSL service provider). Some times my Asterisk queues have trouble contacting the remote agents. At first, I thought I could simply put a SER server on the public edge, but I'm not sure if that will really solve the problem. I question this setup in terms of stability and security. Even worse, what would happen if my boss decides to increase the remote agents?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks again,</DIV><DIV>Waldo</DIV><DIV><BR><DIV><DIV>On Sep 22, 2005, at 7:24 PM, Matt Roth wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">============================================================</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Waldo,</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">- Is your solution 100% Asterisk or are you using other "helpers" such as SER or XXXproxy or whatever?</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">We are not using SER or XXXproxy.<SPAN class="Apple-converted-space"> </SPAN>We are using a Cisco AS5400HPX Universal Gateway to terminate our Ts.
