CUCM Native Call Routing ELIN supersedes all Calling Party Masks?

[orlandoguy82]

If CUCM Native Emergency Call Routing is enabled does the assigned ELIN override all other types of outbound Calling Number masks?

Example: If an outbound emergency Route Pattern or Translation pattern (911) has "Is an Emergency Services Number" selected and enabled and it has a Calling Number mask specified does the ELIN always override this mask? How about at Route Group Calling Party Transformations or SIP trunk Outbound Calls -> Caller Information settings? 

I cannot find this detail in the SRND or other related documentation but it appears that is does.

I did read through this same document but after carefully reviewing it this time I only see one line about this:

"No Calling Party Transformation masks are set at the Gateway or Trunk, because these may transform the ELIN that is set by Emergency Call Handler."

I assume Route Group masking may be used as well in this case. It is not clear on if it supersedes masking at the Route Pattern or Translation Pattern. Meaning does one need to remove any Calling Party Translation Masks that may be on those when enabled the feature.

Thank you for forcing me to read carefully though.
