We don't use the service however, so I can't be much help. We decided to continue using our PRI because I wanted to control echo cancellation. (6Mb EIS, 2 PRI's, and 10Mb NLAN). I will say I am extremely happy with their service. We get a couple hurricanes through the year, and their service never fails.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>I was told that Asterisk was supported when we looked at the service. That It was just a SIP user and Asterisk should register to it. I would assume that they would honor the QoS value in the header. since they are the next hop, they may assign there own value to the packet. They should be able to let you know, if you cal tech support.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I know the QoS value is honored on our NLAN link (Point to Point between locations). </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I would be interested to see how you like the service, if you end up evaluating it. </DIV><DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate;
