[Serusers] SEMS

Hi, I need some documentation for SEMS, havent found none by now. I have it running and working but I would like to explore more possibilities, for instance: Message playback via SIP client or/and Storing the voice message in a folder then sending an email with a http link to it instead of using attach method of/and Compressing the message using MP3/Ogg and so on ... Also: can SEMS be used to provide voice mail messages insted of result codes for failed calls ? Something like "the user is busy", "no such user". I tested addaline.com service, that runs on SER, and they do this. Any help will be appreciated! TNX -- Best regards, Alessio mailto:alessiof@interconnessioni.it
