I still remember our CIO screaming at them on a call (veins popping and all) after our implementation. Some poor fella had to fly in from Canada the next day to smooth things over.<br>

Definitely second the 9600 baud part. Solved a few problems for us.<o:p></o:p></p>

<p class="MsoNormal">Can anyone offer some guidance doing faxing over SIP Trunks? Ever since switching to CUBE SIP trunks I’ve been having challenges with outbound faxes. With one provider, it rarely works, the other it works most of the time but is not reliable.
Sometime it fails and I resend it and works fine. I have an Xmedius Fax Server using T38 with G711 fallback. Feel like I am missing something, I’ve had a few cases open and a mix of fingerpointing (XMedius/Cisco/Provider) and dead ends but no solid resolution.
Just figured I’d ask out here before I escalate these cases again. Both providers use G711 codec on the trunks. When I point the calls pack to MGCP PRI I have no issues.<o:p></o:p></p>
