Significance of $ in dial-peer destination pattern

Posted: October 25, 2006 by cciestudy in Gateways

$ means ”end of digits” and is used for a more specific match. If you have two dial-peers with the same pattern and one with $ and the other without $, then call routing logic will always match the one with $, because that is more specific. Even if you give a lower preference to the dial-peer with $, still it will be matched because by default the dial-plan hunting algorithm is more specific match first and then preference.

dial-peer voice 10 pots

destination-pattern 1000

port 1/0/0

dial-peer voice 11 pots

destination-pattern 1000$

port 1/0/0

preference 5

In this case, always dial-peer 11 will be used to route calls to 1000, even though it has a lower preference.

    It is also important in translation rules where ^ defines the start of a string and $ its end.

    You can also modify the hunt algorithm using global command ´dial-peer hunt´

    so for instance in my case i don’t want the unit to do any dialing, $T in the destination pattern line ( the LEC is going to do the dialing in my case)

    the $ sign stops the __________ timer right away and submits the digits to be processed by the call manager. wondering what timer that would be,
    a> short timer
    b> long timer
    c> it does not expire a timer
    d> there is a different timer that is stopped
