Hi,
I want to have voicemail feature when phone is busy or on no answer

My configuration file is like that:

….
# route block used only to have voicemail if phone is busy or on no answer
route[6] {
  append_branch();
  avp_db_load("$ruri", "$avp(email)/$email_scheme");
  if(!t_write_unix("/tmp/sems_socket", "voicemail/voicemail_headers")) {
    t_reply("500", "error contacting sems");
    return;
  }
  route(5);
  route(4);
  route(1);
}

failure_route[1] {
  # flagset 26 <=> if phone busy we want a voicemail
  if ( (isflagset(26)) && (t_check_status("486")) ) {
    resetflag(26);
    route(6);
    return;
  }

  # flagset 27 <=> on no answer we want a voicemail
  if ( (isflagset(27)) && (t_check_status("408")) ){
    resetflag(27);
    route(6);
    return;
   }
  end_media_session();
}

Now if I use a "default.template" (used by the voicemail module)  with the line:
        from:voicemail@%domain%,

SEMS cannot send correctly a email:
        (3988) INFO: connect (AmSmtpClient.cpp:96): 127.0.0.1 welcomes us
        (3988) DEBUG: send_line (AmSmtpClient.cpp:173): SENDED: HELO 127.0.0.1
        (3988) DEBUG: read_line (AmSmtpClient.cpp:145): RECEIVED: 250 christophe.rv.fr
        (3988) DEBUG: run (AmMail.cpp:119): Mail deamon starting its work
        (3988) DEBUG: send_line (AmSmtpClient.cpp:173): SENDED: mail from: <voicemail@172.20.250.1>
        (3988) DEBUG: read_line (AmSmtpClient.cpp:145): RECEIVED: 501 Bad address syntax

SEMS is trying to send a mail from "voicemail@172.20.250.1" ! The SMTP server doesn't accept an IP and this IP is the IP of the callee SIP device … Strange. It's important to notice that "voicemail" works fine when is used on a phone not registered with the line "from:voicemail@%domain%" in file "default.template" .

In this case the SEMS log file is:
        (4494) INFO: connect (AmSmtpClient.cpp:96): 127.0.0.1 welcomes us
        (4494) DEBUG: send_line (AmSmtpClient.cpp:173): SENDED: HELO 127.0.0.1
        (4494) DEBUG: read_line (AmSmtpClient.cpp:145): RECEIVED: 250 christophe.rv.fr
        (4494) DEBUG: run (AmMail.cpp:119): Mail deamon starting its work
        (4494) DEBUG: send_line (AmSmtpClient.cpp:173): SENDED: mail from: <voicemail@christophe.rv.fr>
        (4494) DEBUG: read_line (AmSmtpClient.cpp:145): RECEIVED: 250 Ok

So I suspect the "%domain%" in "default.template" file is not correctly read by the module "voicemail" after a "failure_route" or after a "append_branch".

What I must change in my OpenSER configuration file in order to resolve this problem ? 

NOTE: I'm using sems-0.1.1 in revision 68

Thanks in advance,
Christophe
