[cisco-voip] MWI with overlapping numbers

[Lelio Fulgenzi]

Why CDR issues?

I'm pretty sure when I look at them, they have partitions listed.

  Total agreement with Justin.  What you have done at this point is introduced layers of translation and complexity that don't need to be there.  A nice design is exactly what Justin suggests below, with the addition of a GateKeeper.  The Gatekeeper will add the filter you need to determine if an extension is on your cluster.

    You will notice other problems with this approach such as:

    CDR issues since CDR is not partition aware 
    CTI issues
    AC issues with line state updates

    I think it would make life easier to use E164 numbers as the DN and use translation patterns within each site to translate four digits to E164. 

    Just my thoughts, and I do realize making this conversion would be a real pain. :)

      Fixed it

      The fix was to change the MWI CSS to search the translation Table instead of each sites local partition. And to change the MWI notification in Unity back to "X"

      Hey all,

      I'm stuck on this one. Here is the scenario.

      IPT customer, with lots of phones. They are using a Centralized model where CallManger and Unity are at the head office providing services for head office and all branch locations. This is a big customer and DN overlapp is a real issue so they decided they wanted to go 4 digit dialing within a given site, and 10 digit dialing between sites. 

      No problem

        a.. I setup each location with a different <sitename>Oncluster Partition and added 4 digit DN's to these partitions. 
        b.. phones can dial each other using 4 digits within a site 
        c.. when they dial another site the must dial 11 digits. example to dial Edmonton they dial 917808885180 
        d.. A translation pattern is used to strip the pattern and search the correct sites partition then strip the 91780888 off the number leaving 5180 
        e.. For centralized voicemail, I used different "VoiceMailProfiles" to prefix the numbers going into Unity so when someone from Edmonton dials into Unity 780888 is prefixed to the 5180 putting them into the correct mailbox. 
        f.. To light MWI lamps, I had to turn Multitenant Mode on so that VM Ports can see the translations created and all works fine
      HERE is the problem

        a.. When someone has the same last 4 digit dn's at different sites, MWI only works for the site who's partition comes first in the MWI CSS 
      Example Calgary phone with DN 4035555180 and an Edmonton Phone 7808885180

        a.. Unity mailbox are as follows Calgary user is 4035555180 and the Edmonton User is 7808885180 
        b.. both message notification feilds under each subscriber have been changed from the default X to 5180 because the actual extension is only 4 digits not 10 (I THINK HERE IS MY PROBLEM BUT DON'T KNOW HOW TO FIX IT) 
        c.. I leave a message for the Edmonton user 
        d.. MWI outbound ports use the Translation pattern to translate 7808885180 to 5180 in the edmOnCluster partition. And tell the phone to dial the lamp code 
        e.. The MWI-ON CSS has partitions in the order of cgyOncluster - then edmOncluster. It doesn't know better it just matches 5180 to the cgyOncluster and the lamp turns on.
      I know you may need a decoder ring to understand this email, but any help is appreciated
