External Phone Number Mask issue in CUCM 8.6

I'm having an issue with External Phone Number Masks in CUCM 8.6

Until recently our DID ranges were all in the 301-713-nnnn range.  Using the EPNM worked successfully providing CallerID.    We have now added some DIDs with the prefix 301-427.

I have set the Route List Detail Configuration to:

Use Calling Party's External Phone Number Mask*  Off

Calling Party Transform Mask   3014279999

However, when I run debug isdn q931 on the gateway the Calling Party Number = '3017139999'.

It appears that the mask 3014279999 is being changed to 3017139999 by Call Manager,  but I do not know where this is happening.   

I do not have any translation  or transformations set.

Thanks all.  I resolved the

Thanks all.  I resolved the issue through further testing.   I had cleared the Caller ID on the Gateway endpoints,  but had not reset the Gateway properly for the change to take effect.  

 

Once I reset the GW with a blank Caller ID, the setting on the Rout List took precedence.

can you explain a bit ... as

can you explain a bit ... as i know on gateway there is option to allow or disable caller id .. we can not manipulate caller id ....

Here is my understanding of

Here is my understanding of the Caller ID.  You can set or change the ID in 4 places:

1.  The DN - set the External Phone Number Mask on the DN on the phone device e.g. if the DN is 1234 and the EPNM is 301713XXXX , the caller ID becomes 3017131234

2. The Route Pattern - you can check the box to use the EPNM set in 1 or leave unchecked and set a mask here in the same way as 1.   A mask set here will overwrite the mask in 1. In my case I want to use the EPNM and I have the option unchecked and no transformation

3. The Route List (Route List Detail) - you can set Use Calling Party's EPNM to ON or OFF or Default.  ON means use the DNs EPNM.  If set to OFF you can set a mask here and this will overwrite the mask in 1. and 2.   I my case I have this set ON to use the DNs EPNM

4. On the Gateway - on the endpoints you can set Caller ID DN in Call Routing Outbound Calls.  This setting overwrites the masks from 1., 2. and 3.   You need to reset the gateway (not just the endpoints) for changes to take effect.   In my case this is blank.  It did have a value of 301713XXXX.  When I removed this I failed to reset the gateway to the setting was still active causing my issue
