color:#1F497D;">I have helped to design, architect and deploy multiple customers
with SIP, including SIP trunks carrying contact center calls and also business
user calls. I helped to build out the initial infrastructure of a global
medical device firm that almost has all of their US remote offices –
literally 100s – migrated onto their centralized SIP trunks. </span></p>

speak a slightly different dialect. However, with the onset of some very
nice Border Gateways – it is making this a non-issue. However, as Matthew
states below – you need to work with someone who knows what they are
doing.</span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"sans-serif";

simply a wash and at other times can save a tremendous amount. Like the
example above, each of the remote sites had a least a PRI. However, many
of the offices hardly used 12 b-channels. By centralizing, they are
seeing a very nice savings and they get:</span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"sans-serif";
color:#1F497D;">The thing I would say is it all depends on your level of comfort
with the Carrier and with SIP. I generally don’t have a problem with the
quality of the service when it works, the problem has been troubleshooting and
making it work in the first place. I understand how to debug and troubleshoot a
T-1 or PRI and can set one up H.323 or MGCP no problem. SIP just doesn’t
process for me, Everybody says it’s simple, plain text and all that but I
don’t get it. </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"sans-serif";
color:#1F497D;"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"sans-serif";
color:#1F497D;">My point, If you are going with it make sure you or someone you
have understands it.</span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"sans-serif";
color:#1F497D;"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"sans-serif";
color:#1F497D;">If you have a smaller install one thing you can do is have the
provider put in an IAD and hand off as PRI. Make them responsible and make your
side something you understand. Obviously in a large campus environment that may
not be feasible and defeats some of the consolidation benefits but in a smaller
setup it can make life much easier.</span></p>
