Field Description Usage tips
Call time to
live
The interval (in seconds) at
which the VCS polls the
endpoints in a call to verify that
they are still in the call. Default
is 120.
If the endpoint does not respond, the call will be disconnected.
The system polls endpoints in a call regardless of whether the
call type is traversal or non-traversal.
Auto
discover
Determines whether it will
respond to Gatekeeper
Discovery Requests sent out by
endpoints. The default is On.
To prevent H.323 endpoints being able to register automatically
with the VCS, set Auto discover to Off. This means that
endpoints can only register with the VCS if their Gatekeeper
Discovery setting is Manual and they have been configured with
the VCS’s IP address.
Caller ID Specifies whether the prefix of
the ISDN gateway is inserted
into the caller's E.164 number
presented on the destination
endpoint.
Including the prefix allows the recipient to directly return the call.
