Description

Quintum’s Tenor Call Relay™ provides a single VoIP portal between IP networks allowing for end to end VoIP communications across multiple IP networks. All calls are switched through multiple IP networks with just one single compression and decompression of the voice. The result is less latency and higher voice quality as the call passes from network to network.

The Tenor Call Relay allows VoIP endpoints such as VoIP gateways, IP phones and IP soft phones which are behind a Network Address Translation (NAT) firewall, to communicate with VoIP endpoints on external IP networks. This allows both enterprises and service providers to expand their VoIP networks to home offices, branch offices, customers, partners, and across the public Internet.

Tenor Call Relay also provides a single point for call management, administration and security at the edge of your VoIP network. With this unique intelligent VoIP network switching, the Tenor Call Relay makes expanding VoIP calling both easy and risk free. Call Relay is available in two versions: Standard version supports up to 32 simultaneous VoIP calls; Call Relay SP supports up to 720.

More intelligence means higher voice quality and less delay When separate VoIP networks are linked using circuit switched connections, the multiple compression and de-compression processes that occur increase transmission delay and cause unnecessary degradation of the voice quality. Tenor Call Relay eliminates these delays with its direct IP connection between VoIP networks, thereby increasing voice quality.

More intelligence eliminates firewall issues With NATAccess TM the Tenor Call Relay is able to pass VoIP traffic from internal end points transparently through your IP networks’ NAT firewalls. More intelligence means less network congestion.

With its PacketSaver™ technology, the Tenor Call Relay reduces bandwidth consumption of VoIP calls by multiplexing multiple calls into the same packet, reducing the overall bandwidth utilization by up to 50%, beyond voice compression and silence suppression.
