PERATOR
You can define an IP network endpoint as an IVR operator and configure the
LifeSize Gateway ports accordingly. See
Configuring IVR Settings on page 70
for more information.
Dialing Example 7: Direct dialing to an IP network endpoint (LifeSize Gateway
supports DID)
The number string 5645001 is a call from an ISDN network terminal to an IP
network endpoint. This number string consists of:
5645001—The destination endpoint phone number.
The call is routed to the requested endpoint according to its registration identity
in the gatekeeper.
Dialing Example 8: Direct dialing to an IP network endpoint (LifeSize Gateway
supports TCS4 but not DID)
The number string 5645000^5776 is a call from an ISDN terminal to an IP
network endpoint. The dialing endpoint must also support TCS4. This number
string consists of:
5645000—The LifeSize Gateway phone number.
^—The TCS4 delimiter of the dialing endpoint (if required).
5776—The extension number of the requested endpoint.
Note TCS4 only routes H.320 video calls.

IALING THROUGH
THE
IVR
When the LifeSize Gateway does not support DID or TCS4, you can reach an
endpoint using the Interactive Voice Response (IVR) routing mechanism.
When IVR is enabled, you are answered by a recorded message prompting you
to enter the destination endpoint phone number followed by the pound (#) sign.
If you enter the number of an endpoint that is online and currently not busy, the
IVR connects the call to the requested endpoint.
Dialing Example 9: Dialing to an IP network endpoint through the IVR
The number string 5645000 <wait for the IVR to respond> 5561# is a call
through an IVR routing mechanism. This number string consists of:
5645000—The LifeSize Gateway phone number.
5561—The number of the requested endpoint.
#—This is required by the IVR for call completion.
