Dial Zero Call Manager 9.x

Wondering if anyone has done anything where you Dial Zero from different sites and have the Zero go to different locations but the phones are using the same CSS's at different locations.  We are settting up the enterprise and trying to keep the CSS's standard and not create CSS's for each locations as everyone is sharing centeralized PRI's. For example what I would like to do is have 2 phones using the same Long Distance CSS's at different locations dial Zero but end up at different locations.  We are using Local Route Group for 911 routing with in the Device Pools and I am trying to figure out if we can do something similar for Zero.  Mabye route Zero based on the Device Pool?  Would it be possible to have Zero route through contact center and have contact center do a lookup on the phone's Device pool and route based on that.

Thanks for any advice in advance.

Hi,

You can actually do this using just Translation Patterns by using the Route Next Hop By Calling Party Number option.

In the example below assume site A uses DNs in the 1XXX range and the site operator has DN 1000 and

site B uses DNs in the 2XXX range and the site operator has DN 2000

First create a partitition DIAL-ZERO-XLATE_PT

Next create a calling serach space DIAL-ZERO-XLATE_CSS and add the new partition to it.

Now create a Transaltion Pattern with the settings below:

Translation Pattern:     0

Partition:     INTERNAL_PT (a partition that all the phones can access)

Calling Search Space: DIAL-ZERO-XLATE_CSS

Route Next Hop By Calling Party Number: ticked

For site A create a Transaltion Pattern with the settings below:

Translation Pattern:     1XXX

Partition:     DIAL-ZERO-XLATE_PT

Calling Search Space: INTERNAL_CSS (a CSS that allows calls to the DNs associated with site operators)

Route Next Hop By Calling Party Number: unticked

Called Party Transform Mask:  1000

For site B create a Transaltion Pattern with the settings below:

Translation Pattern:     2XXX

Partition:     DIAL-ZERO-XLATE_PT

Calling Search Space: INTERNAL_CSS (a CSS that allows calls to the DNs associated with site operators)

Route Next Hop By Calling Party Number: unticked

Called Party Transform Mask:  2000

I have tested this and it works just fine. The important thing to understand is that the first translation pattern instructs the site specific translation patterns match against the calling number. You need to set Route Next Hop By Calling Party Number on the first translation pattern only.

Hope this helps!

Cannot be done unless the zero destination is outside of CUCM where Local Route Group can be used.

IF the destination is simply a translation pattern pointing to another phone/CTI RP/etc you will need separate CSSes.

Yea I was thinking that was the option but thought just maybe there would be "creative" way to get around it.  What about using Contact Center to lookup the phone's device pool and route based on that not sure if that can be done.

You could use Local Route Groups to add some digits and send it to Contact Center and then distinguish between sites based on the prefix digits.

Take a look at this thread, you can apply this logic, where you basically build RG pointing to a SIP trunk that loops onto the CUCM, I don't know if this is supported, but I have seen other threads using similar logic:

I missed the last sentence about contact center, do you have UCCE or UCCX?

You can certainly do a DN lookup on either one, if the sites have specific DN prefix it would be very simple. If this is UCCX you cannot use local route group as you connect to the UCCX via CTI RP which is an internal destination and does not use RP. With UCCE you can route the call to CUSP/CVP via Route Pattern.

HTH,

Chris

We have UCCX

How are DN constructed at each location, are they in consecutive ranges or random extensions at each site?
