Hey list,
 
According to the UCM SRND the calling party transformation patterns are to be 
matched with the result of the transformations performed at the RP/RL level:
 
*********************
The calling and called party numbers resulting from the digit transformations 
configured in the route pattern and/or route lists are then processed by any 
Transformation Patterns configured for the devices contained in the chosen 
Route Group. 
........
If you are performing several digit manipulations in a route pattern or a route 
group, the order in which the transformations are performed can impact the 
resulting calling and called party numbers used for the call. Unified CM 
performs the following major types of digit manipulations in the order 
indicated: 
1. Discarding digits 
2. Called/calling party transformations 
3. Prefixing digits 
4. Called/calling party transformation patterns 
*********************
 
However, this seems not to be the reality at least when a call is routed 
through a RP pointing to a RL containing h.323 or mgcp gateways. Furthermore, 
the lab 5c PG states (page 204) that "The calling party transformation pattern 
match is based on the calling number at the point the route pattern match took 
place", so a TP had to be inserted in between the DN and the RP to transform 
the calling number and not match the already created calling transformation 
pattern, and finally sort out the task 5.4. 
 
In contrast, when testing with a RP -> RL in which there is a sip-trk, the 
results are more close to what the srnd states, i.e the RP calling party 
transformation result is matched with the calling party transformation patters 
set for the gw; with the exception that calling party transformations performed 
on the RL level the results are ignored by the calling party transformations 
patterns. So at the end there are mixed results (at least with the testing I've 
been doing), and I couldn't come with a clear conclusion of what should be 
happening...,
 
If the SRND is correct, would the current ucm behavior represent a bug?, if the 
PG is right, please kindly explain the process further and give some docs 
references in order to get a better understanding,
 
Help very appreciated,
 
Otto
