Company’s IP-Based HDX and SLICE 2100 Softswitches Fully Interoperable with Polycom Handsets

REDCOM Laboratories Inc., a company that designs and manufactures the world’s most reliable digital and IP-enabled telecommunications systems, announced today that it has completed Session Initiation Protocol (SIP) interoperability testing for REDCOM’s HDX and SLICE® 2100™ Carrier-Class 4/5 softswitches with a wide range of SoundPoint® IP phones from Polycom, the global leader in telepresence, video and voice communication solutions.

REDCOM tested several Polycom SoundPoint® IP models (320/321/330/450/550/560/650/670), as well as the VVX® 1500 Business Media Phone for verification in REDCOM’s lab to ensure that the company’s HDX and SLICE 2100 softswitch solutions are fully interoperable. REDCOM successfully provided rigorous and comprehensive SIP interoperability testing in its company lab in Victor, which verified 100 percent integration and functionality between the Polycom VoIP phones and REDCOM’s HDX and SLICE 2100 SIP call control platforms.

“SIP is supposed to be a standard that eliminates many of the challenges with integrating systems from different vendors, but interoperability is not something that can be assumed or taken for granted,” said Gerald Totsline, Director of Engineering, REDCOM. “SIP interoperability testing is a good method of verification to ensure that when two SIP-based solutions are actually deployed that they will work together flawlessly. In our lab tests, what we found was a seamless, problem-free integration that verified interoperability between the Polycom SIP endpoints and the REDCOM SIP call managers. These SIP-based products from Polycom and REDCOM are totally interoperable.”

Based on this verified SIP interoperability between the Polycom IP handsets and SIP-based REDCOM HDX and SLICE 2100 softswitches, commercial customers will be able to deploy these best-of-breed VoIP solutions with confidence and without compromising functionality. REDCOM’s HDX and SLICE 2100 are powerful softswitches and SIP call managers that retain complete Class 4/5 capabilities in a single platform solution.
