[SIPForum-techwg] Real Interoperability

[Dan York]

+1

We need a spec that is extremely simple to test and that is blindingly  
clear on what constitutes "SIPconnect 1.1-compliant".  In my mind,  
ideally someone should be able to create an automated test tool that  
mimics one end of the "SIPconnect 1.1" IP-PBX to SSP connection so  
that vendors can test their product against that tool.  (Perhaps there  
can be two such tools, one for either end.)  The fewer SHOULDs and  
MAYs you have, the more likely you can get to this state... and the  
more widely supported the spec can be.

My 2 cents,
Dan
