A more intelligent way to switch VoIP calls
among different IP networks
Tenor Call Relay offers:
• VoIP switching between IP networks
• IP endpoints behind the NAT firewall
• PacketSaver™ that minimizes bandwidth requirements
• Up to 720 simultaneous VoIP calls
• Standard and High Capacity Service Provider (SP) versions
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™ 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.
