Connect On Call Proceeding
3.123 (For trunk ports only.) This flag affects outgoing Basic or Primary Rate ISDN calls. If it
is enabled, the system will connect the B-channel as soon as the Call Proceeding message is
received from the Central Office [local exchange] interface. Some Central Office [local
exchange] interfaces, especially SS7 interfaces, do not send progress indicators when they are
playing tones or announcements on the B-channel. They play the tone or announcement prior
to sending the progress message, after the call proceeding. In this case, if the flag is disabled,
the user experiences audio clipping. If the flag is enabled, the channel is opened when the call
proceeding message is received and the system does not have to wait for a progress indicator
(indicating alerting, busy, reorder tones or announcements).
Retry ARS Call If Call Rejected
3.124 (For trunk ports only.) This flag is for ISDN messaging for outgoing calls using ARS. If
set to
Yes, the system will retry the additional channels and trunk groups programmed in ARS
if the call is rejected by the telco when receiving a specific cause value.
3.125 The symptom that will appear because of this flag is when an outgoing call is rejected
by a telco, where it causes the system (via ARS) to cycle through all the ISDN channels before
releasing/disconnecting the call.
3.126 This flag is enabled by default. The flag should be disabled on Pubic ISDN circuits con-
nected to a telco. If not using ARS with ISDN services, this flag does not apply.
3.127 When this flag is set to
No, the system will not retry the ARS call, regardless of the rea-
son it was rejected. If this flag is set to
Yes, the system will retry the ARS call as long as the
cause of the rejection is NOT one of the following causes:
• Unallocated or unassigned number
• User is busy
• No user is responding
• Call rejected
• Number has changed
• Destination is out of order
• Number format is invalid
• There was a temporary failure
• Congestion in the switching equipment
• Requested circuit/channel is not available
• Outgoing calls are barred
• Incoming calls are barred
• Service or option not available, unspecified
• Service or option not implemented, unspecified
• Mandatory information element is missing
• Interworking, unspecified
