Developer Solutions
The award-winning RADVISION SIP – H.323 Inter Working Function is a versatile communication solution for the evolving VoIP market.
  
Once leading the way in VoIP communication throughout the market segment, H.323 is now gradually being replaced by SIP as the dominate signaling protocol for VoIP Call Control.

SIP has been adopted by 3GPP and TISPAN standardization bodies as the fundamental signaling protocol for next generation architecture. The H.323 architecture of Enterprise and Carrier networks is being gradually replaced with SIP and IMS architecture.		  

The SIP – H.323 Inter Working Function solution by RADVISION is positioned to solve the H.323 – SIP interworking for Unified communication vendors,
Enterprise communication manufactures and PBX vendors

However, H.323 is still being massively deployed. Since many enterprises are hesitant to migrate from existing H.323 communication systems, losing their capital investment in H.323 communication equipment, vendors are looking for ways to integrate new SIP phones and SIP services into their existing H.323 infrastructures.

"The benefits provided by the services team showed itself in two areas. The first was on the price ffont.
The price per port provided on the Enterprise-CS is great. we couldn't have hit these price levels without the RADVISION stack and professional services team. The second benefit appeared on the time to market front."
