<DIV><FONT face=Arial size=2>From our initial conversations with our PSTN
providers, SIP was a few years away with feature parity with H323/MGCP/PRI
trunks.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>FAX support was definately out of the question, and
there were crazy requirements about not being able to do voice only on the
ethernet trunk. We had to buy a data package that was no more than 50% voice
traffic. For us, we get our internet through our regional network at dirt cheap
prices because we basically run a co-op. For others it might make sense to move
to the same PSTN/SIP/Internet carrier, but for us it didn't. Even our backup
internet link is cheaper than the PSTN provider could price I
believe.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The other thing was route diversity and multiple
demarcs. I think those were quite expensive where as now, we get it at no extra
cost.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've long been a proponent of if it ain't broke,
don't fix it. Even when we went to tender and ended up switching our PRIs to
another local carrier, it was a LOT of work. I understood it saved us
quite a bit of money, so it was worth it in the end for a three year
contract. That being said, don't expect that SIP will be cheaper than PRIs
and/or without it's own problems.</FONT></DIV>

<DIV>I assume you are talking traditional analog and digital PSTN
gateways, why are you considering migrating to SIP to
control these as opposed to H323? .</DIV>

<DIV><BR>Has anyone started using SIP on the PSTN gateway? I want to use
it instead of H.323 or MGCP and start migrating it to SIP on the gateway.
Any experience with this? Can I get Calling Name and Number from the PSTN
side? </DIV></DIV><PRE>************************************
