Telchemy, NexTone News

A natural partnership between Telchemy, a VoIP performance management company and NexTone a session border controller maker has recently taken place.

Specifically, NexTone will feature VQmon/SA (Stream Analysis) call quality analysis algorithms in its MSC product for carriers and enterprises to use in monitoring, diagnosing, and managing network call and packet-related problems. NexTone's MSC enforces QoS policies across the network edge, thus enabling carriers and enterprises to route, manage, and control real-time traffic at minimal cost.

NexTone's MSC is deployed at the network edge and operates alone or in conjunction with a core call control engine such as the NexTone Multiprotocol Signaling Switch (MSW).  The MSC's FlexPeer capabilities, consisting of dynamic call admission control, SIP/H.323 interworking function, network address translation (NAT) and VoIP firewall functionality, provide IP carriers with flexible, secure interconnections to other IP-based carriers and enterprises.

Telchemy's VQmon/SA is used in mid-stream routers and switches and in VoIP test equipment, e.g., probes and analyzers, to support both non-intrusive monitoring of live calls and active test calls for on-demand troubleshooting. It further supports the Internet Engineering Task Force (IETF) RFC 3611 (RTCP XR) Protocol and the new QoS reporting protocols for International Telecommunications Union (ITU) H.323, H.248 and G.799.1 standards. VQmon/SA provides:


Listening and conversational quality metrics

MOS scores and R factors
Detailed packet/RTP statistics
Jitter buffer emulation
RTCP XR encoding/decoding with dynamic calibration

It should be a matter of time before other session border controller manufacturers make similar announcements.
