How to use Timeout and Termination Characters in Call-Routing Tabels
Posted by Elena Brambilla, Last modified by Daniel Lizaola on 12 December 2017 04:53 PM
Call-Routing tables offer two possibilities to terminate overlap dialed numbers.
1. A dialling timeout
2. A special termination caracter like # or *
The timout and the caracter can be configured as follows:

172.16.40.125>enable
172.16.40.125#configure
172.16.40.125(cfg)#context cs
172.16.40.125(ctx-cs)[switch]#digit-collection timeout 5
172.16.40.125(ctx-cs)[switch]#digit-collection terminating-char #

For example:
172.16.40.125(ctx-cs)[switch]#routing-table called-e164 RT-CDPN-EX
172.16.40.125(rt-tab)[RT-CDPN~]#route 123T dest-interface Line0

According to this rule the dialed keys '12345#' will be immediatly matched and the number '12345' will be used without waiting for the timeout.

Special Cases:
The Termination Character can also be part of the rule, in which case it will NOT have the effect of cancelling the timeout period.

Examples:
Rule: #21#T
Dialled Keys: #21#1234
Effect: Timeout is aktive, used number: #21#1234

Rule: #21#T
Dialled Keys: #21#1234#
Effect: No Timeout, used number: #21#1234

Note: The first two dialled '#' do not cancell the timeout, they are part of the rule.

For a general digit-collection with timeout or termination caracter without any restrictions use the following rule:
Rule: T

In this case...
Dialled Keys: 1234
Effect: Timeout active, used number: 1234

or...
Dialled Keys: 1234#
Effect: No Timeout, used number: 1234

Do NOT use a rule as follows:
Rule: .*T

In this case...
Dialled Keys: 1234#
Effect: Timeout is STILL active because '#' matches the regular expression '.T', the used number will be: 1234#
