a. Implicit: As part of routing process ○ Translation Pattern ○ Route Pattern ○ Route Lists
a. Explicit: Transformation after routing decision ○ Incoming Calling/Called Party Settings on gateways, trunks (or device pools) ○ Calling/Called Party Transformation CSS on gateways, trunks (or device pools) ○ Calling Party Transformation CSS on phones (or device pools)
As the call is being processed, the order by which digit manipulation applied is as follow:
You can see that the closer to the gateway, the higher the precedence of the manipulations. It is important to remember that if you manipulate on RP without modifying RL-RG manipulations (left them as default values), RP manipulations will take effect. If you modify any parameter in RL-RG manipulations (even if one), RP manipulations will be fully ignored. Same is applicable with Xformation Patterns and RL-RG manipulations.
Let's assume that you changed 'Calling Party Transform Mask' under RP > Calling Party Transformations and changed 'Called Party Number Type' under RL-RG > Calling Party Transformations, in this case all settings under RP > Calling Party Transformations will be ignore including 'Calling Party Transform Mask'. The settings under RL-RG > Calling Party Transformations will be used even the empty one for 'Calling Party Transform Mask'.
Let's assume that you changed 'Calling Party Transform Mask' under RP > Calling Party Transformations and changed 'Called Party Number Type' under RL-RG > Called Party Transformations, in this case all settings under RP > Calling Party Transformations will be used and all settings under RL-RG > Called Party Transformations will be used.

Hi all, We have 7931G and 7965G phones in our network. They authenticate via CAPF signed certificates (LSC) for SIP-Secure. At present they use SHA1 signed certificates. According to this Cisco Live, both these models should support SHA2 ce...
Hello everyone,We are upgrading our CUCM cluster to version 11.6 and would need to replace about 10000 phones. The phone replacement is going to happen before the upgrade of CUCM. We have more than 20 phone services configured in our CUCM cluster. Each ph...
