[Serusers] Precall Speech with SER and SEMS

[matt morris]

Hello List,

I would like to implement a precall speech feature with SER with possibly 
SEMS. Basically for a certain of group of our user we would like them to 
hear an audio before establishing their calls with the callee. However, I 
don't have much clues on how to do this. I have tried the Asterisk B2BUA by 
Mr. Mike Tkachuk (which worked) but I don't want the media stream to be 
handled by the B2BUA. Unfortunately, I do not know how to configure a 
signalling-only B2BUA with the playback - seems whenever I used the playback 
function in Asterisk and subsequent call media will be have to be handled by 
Asterisk.

That is why I want to explore the possibility of another approach with SEMS. 
Would it be possible for the call to be first forwarded to the SER+SEMS box 
to play the announcement AND THEN forward the call to the actual called 
number? Please shed some light on how I could make this happen. Thank you 
very much.
