bigger bang for out bucks. We have 2 – 20 Meg pipes which is 2 – 300 path trunks. With G.711 we will only get about 2 – 155 (Math in head conversation) path trunks.

we need to finish T.38 on that set of routers before we go permanent on the SIP trunks.

<br>
Does AT&T's SIP service not support G.711? Or are you simply trying to squeeze more channels onto limited bandwidth? (Get more bandwidth.)<br>

<p class="MsoNormal">Anyone else have the feeling SIP isn't all it's cracked up to be? In our case, if you're not already getting Internet service from your your SIP provider, it's just not that economical. Especially if you have to keep a PRI around for faxing,
modems, alarms, etc. <br>
