Use Record user announcement in strategies

Hi. I am trying to record an announcement through IRD and it works fine, but it is always recorded with a filame name that contains an ID and I would like to know if it is possible to record the announcement without it.
I want to use this announcement later in another strategy, but up to now I was not lucky.

I have SIP Server and MCP 8.1.

I have tried with the following formats in USER_ID:

msje
msje.wav
msje-1.wav

but the final result is:

msje-‘id’-.wav
msje.wav’id’-.wav
msje-1.wav’id’-.wav

I will appreciate very much any help

No, it is not possible. If the ID is missing, you will not be able to play this annoucement at all from anywhere.

Thank you very much!
