Speaking of SIP, this press release is kind of weird: Telesphere's Ecosystem Partners Equals Leadership in Cloud Communications. They burned through $50M. Acme Packet plus Broadsoft is no secret sauce. A little FMC (fixed mobile communications) from Varaha. The same hardware suppliers as everyone else: ADTRAN, Cisco and Polycom. Same carriers supplying DID, SIP trunks, etc.: Level3, Global Crossing and XO Communications. It mentions an ecosystem that basically everyone in the Cloud Communications Alliance has also.
It's good to put out PR, but craft a message that resonates with your marketplace. It has to tell a story that people want to hear.
