Quintum’s Tenor Call Relay™ Session Border
Controllers provide a VoIP conduit between IP
networks allowing for end to end VoIP communica-
tions 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 enter-
prises 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.
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 means greater efficiency
and security
Tenor Call Relay comes with a Gatekeeper option* for
registration of IP endpoints and phones within the local
zone. Calls within the zone are routed directly between
endpoints; Calls out of the zone pass through the Call
Relay for maximum security.
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 57%,
beyond voice compression and silence suppression.
