About Gateway Features
Quality of service (QoS) The LifeSize Gateway features configurable coding of
media packets to achieve QoS routing priority on the
Internet Protocol (IP) network. The Type of Service
(ToS) bits of the IP datagram header can be configured
for priority level.
Dial plan The LifeSize Gateway supports a simplified dial plan for
outbound dialing using a single universal prefix. Using
the dial plan, the LifeSize Gateway automatically detects
the capabilities received in the Setup message from the
IP endpoint and sets the same bit rate for the ISDN (or
serial interface) side of the call.
Direct dialing and call routing The LifeSize Gateway dial plan supports the following
direct dialing and call routing facilities:
Direct Inward Dialing (DID)
Multiple Subscriber
Network (MSN)
Q.931 Sub-addressing

Access control The LifeSize Gateway features password-controlled
access to the LifeSize Gateway interface. Up to ten
different administrator access profiles can be defined for

DTMF translation The LifeSize Gateway supports translation between
in-band Dual Tone Multi-Frequency (DTMF) signals (on
the ISDN side) and out-of-band H.245 messages (on the
IP side). DTMF translation occurs for voice and video
calls.
