[Serusers] Implementing Voicemail

[Jiri Kuthan]

The key fragments of SER script with voicemail support are as follows:

if (uri==myself) { # vm only for my domain ...

  /* if this is an in-dialog request from voicemail, jump out of
     proxy mode and pass the request to voicemail; you need to have
     'user_prefix_separator=+' in sems.conf
   */
  if (uri=~"sip:voicemail\+@") { 
                /* some transaction processing to absorb retransmissions;
                   the key part is "vm", which passes requests to the
                   SEMS machine (we should better integrate all this stuff
                   in a single command someday, sorry scriptwriters
                */
                t_newtran();
                t_reply("100", "trying -- just a second");
                if (!vm("/tmp/am_fifo","announcement")) {
                        t_reply("500", "SEMS error");
                };
                break;
  };

  if (!lookup()) { # user off-line?
             if (method=="INVITE" || method=="ACK") {
                       t_newtran();
                       t_reply("100", "trying -- just a second");
                       if (!vm("/tmp/am_fifo","announcement")) {
                             t_reply("500", "SEMS error");
                       };
                        break;
              };
              # non-VoIP methods for off-line users will just
              # just return 404
              sl_send_reply("404", "Not Found");
              break;
 };
 # continue with online users.....

That's it, very briefly.

You can improving by handling users who are on-line but whose
requests fail downstream (no reply timeout,busy,etc.)

If all is set up properly, the recepient will receive the message
by email/
