Products / Quintum VOIP gateways / Tenor Call Relay Session Border Controllers

Quintum's Tenor Call Relay™ Session Border Controllers provide a VoIP conduit 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 networks on other 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, Tenor Call Relay makes expanding VoIP calling both easy and risk free. Call Relay is available in two versions: Enterprise Call Relay 60 supports up to 60 simultaneous VoIP calls; Call Relay SP supports up to 672.
