[cisco-voip] Trying to understand partitions, calling and called transformations

Thu Oct 21 13:02:16 EDT 2010

I agree with using the device CSS.  However, it sounds like you are
trying to implement AAR in the event of a WAN outage (if you have all
phones registered to a centralized CUCM cluster).  If that is the case,
then there is configuration on the gateway that u need to do for when
folks at the remote site dial 4 or 5 digit numbers back at the main site
(which won't work if the WAN is down) so that it is prefixed with the 1
(if it is long distance) and the required prefix digits.  Also, you
would need to create AAR groups for the remote site(s) as well as the
main site so that when the WAN is down, and a phone from the main site
or other remote sites try to call the remote site, AAR will prefix it
with numbers set in AAR.  You also have to ensure either the phone line
is configured with the correct phone mask for the line or configure the
AAR mask for the phone...if AAR mask is configured, I believe it
overrides the External Phone mask configuration when AAR kicks in.

Here are some links on AAR.

The route pattern should have a partition.  the route pattern should
point to the RL --> RG (get the transformation mask) --> VGW.

Now I would use the CSS on the phone rather then just the DP CSS.  as
more info as you move forward there is a CSS on both the phone device
and Line.  The two combine to give you an over all CSS.

What are you trying to do with your transformation mask?  is this to
prefix going out?  or is this the caller ID going out?

you can see on the voice gateway what it's doing going out by doing a
debug isdn q931.  This might help in troubleshooting.

Its' starting to make sense.

So my goal here is to assign a different Calling Party Translation
Mask to the 3 different groups of phones I have.

1 - Create a route group (assign the gateway to this, as I only have 1
gateway for everyone)
2 - Create a route list (add the route group i just created, then
click on the route list details and assign the calling party
transformation mask (1015551234) )
3 - Create a device pool for each location and assign the route group
to the respective device pool (local route group option)

So if a device is assigned to the correct device pool, the calling
party transformation mask should apply accordingly.

Only problem is it doesn't work.   Am I missing something?

Thanks,
Dan.
