Can somone explain differances between SER and ASTERISK.
SER is a SIP Proxy. It doesn't deliver any phone services. SER never handles the media stream. (The RTP proxy may, but that's another story...)
Asterisk is a PBX, it answers and originates calls and tries desperately to stay in the media stream to be able to deliver IVR services. Asterisk is multiprotocol and can handle PSTN termination over PRI and BRI as well as analog lines.
I am particularly interested in functionality that is not available with ASTERISK but SER can provide.
SER is a full SIP proxy with support not only for phone calls, but for all other types of SIP sessions, like a game of chess, a whiteboard session, instant messaging... Ser opens up the wonderful global world of SIP, where Asterisk handles phone calls, and does it very well, indeed :-)
