[cisco-voip] [OSL | CCIE_Voice] Plz help, anyone knows the order of operation of Calling party transformation patterns in CUCM 7.0.1?

[Berry, Matthew J.]

Jeremy -

It's important to remember that translation pattern modify the number whereas route patterns and route lists do not. Once the modification takes place, as a call passes from an internal IP phone toward the gateway, the transformations at each point can be overridden. The called/calling parting transformations applied at the CUCM gateway configuration will always override the settings before it.

Hi Jeremy,
You got this answer from Otto Sanchez on your other post on the same topic.

"Hello Jeremy,



I think that an important fact to know is that cg/cd xform patterns get

matched at the time the rp is being hit, so cg/cd xforms will override the

transformations you perform at the rp level,



If you configure the EPNM in a TP, the cg number getting to the rp will be

the globalized number, right?, in this case, a cg xform pattern will be

matched only if it corresponds to that EPNM,



Please let me know if this clears up things a little bit for you,"



I would say that the answer you got is pretty strait forward, but if not test it out in all sort of ways in your lab and I think it will click for you.

well, I know this order but CngPTP break these rules.

Check out this scenario:   call---->TP---->RP-----------> SLRG----->GW

,check EPNM on TP and RP ,put CngPTP on GW.    it overrides.
,check EPNM  only on RP ,put CngPTP on GW.    it does not override.
,check EPNM  only on TP  ,put CngPTP on GW.    it  overrides.



How these mess works with CngPTP?

The farther down the chain you go the override happens. So:

gateway overrides RL
RL overrides RG
RG overrides RP
RP overrides phone

Pretty sure about this, but I'm sure someone will chime in.

Hi,

Anyone knows how calling party transformation pattern order of operation in CUCM 7.0.1?


I just got confused and docs are pretty weak in this area.   It should override RP,RG,RL configuration. But apparently it would not!

What is the relationship of checking EPNM on TPRP,GW and CngPTP ?



I really appreciate any comment on this. Any doc that explain this relationship?

Cheers

Jeremy
