Chapter 15-Gateway Calls
15-10
Connection Indications
During the connection process to the other endpoints, the system displays
on the calling participant’s screen the called number and the connection
status.
A Maximum of 32 characters can be displayed for connection indications.
If the displayed information is longer than 32 characters the text is
truncated.
If the system dials out to only one destination endpoint, the dialed
number is not shown, only the connection status.
If the destination endpoint is ISDN, the system displays the connection
progress in percentages, where the percentages represent various stages
in the connection process as follows:
Up to 60% the connection of the ISDN channels (up to 30 channels
can be connected when E1 is used for the connection).
60% - 80% BONDING stage
80% - 90% Capability exchange stage
90% - 99% Media connection stage
Once the call is completed, the indications are cleared.
If the call is not completed after trying all possible protocols, the system
displays the number that was dialed on the calling endpoint’s screen and
one of the following causes:
Busy - the far endpoint is in another call. In such a case, the system
does not try to connect using another communication protocol.
Rejected - the far endpoint has rejected the call. In such a case, the
system will try to connect using another communication protocol.
Unreached - the number could not be resolved by the gatekeeper or
the SIP proxy or could not be found on the network. In such a case,
the system will try to connect using another communication protocol.
Failed - any reason causing the system not to complete the connection
process. In such a case, the system will try to connect using another
communication protocol.
You can hide the connection indications by changing the system
configuration. For more details, see "Displaying the Connection Information -
System Configuration” on page1-1 .
