Hey everyone, I could use a little help/advice regarding VoIP phones. I have a VoIP provider that lets me use any software I want with their services (I think they call it SIP). Anyway, I need to find a program for Windows that I can use which will allow me to play an mp3 as if it was coming from the mic. The reason for this is because when someone doesn't answer the phone, rather than have to speak through a voicemail script, I'd rather have one recording and just play that recording and leave it on their voicemail. If anyone knows of a program that can do this that's compatible with VoIP accounts, or heck, at this point I'd even take something compatible with Skype, please PLEASE let me know! Thanks!
