Hi, I was searching on SIP Trunking, and found the SIP SOPHIA discussion list (please, see below). I thought that someone here has been trying to meet the recommendations of the SIP connect 1.0. rgs Cesar ========================================================================================================================================================================= More or less, sofia is the only one that both fit my ideal model of a SIP UA *and* can handle the call volume in sip traffic that matches the boxes capabilty every other stack we tried would buckle under the stress and deadlock, crash, run up the CPU or run out of memory. I don't know of any such comparison page, sorry.

Although I wonder why existing implementations are not suitable for you. As we know there are plenty of open source PBX, SIP proxies, and softswitches out there. Cheers Benny
