Announcement then call transfer
|
|
|
|
This application plays an announcement and then REFERs the caller
|
|
to either the uri configured in P-Refer-To header, or if his is not
|
|
configured, the request URI of the first INVITE.
|
|
|
|
If refer is not accepted, succeeds, or fails, a BYE is sent.
|
|
|
|
Example ser configuration appends:
|
|
|
|
#appends: parameter for announce_transfer
|
|
modparam( "tm", "tw_append",
|
|
"announce_transfer_headers:P-Refer-To=avp[$refer_to]")
|
|
|
|
# appends for REFER NOTIFYs
|
|
modparam( "tm", "tw_append",
|
|
"notify_headers:hdr[Content-Length];hdr[Content-Type];hdr[Event];msg[body]")
|
|
|
|
Example of invoking announce_transfer within route:
|
|
|
|
if (method != "ACK" && method != "INVITE"
|
|
&& method != "CANCEL" && method != "INFO"
|
|
&& method != "NOTIFY" && method != "BYE" ){
|
|
log("unsupported method\n");
|
|
sl_send_reply("500","unsupported method");
|
|
break;
|
|
}
|
|
|
|
if (method == "NOTIFY") {
|
|
if (!t_write_unix("/tmp/sems_sock","announce_transfer/notify_headers")){
|
|
log("could not contact announce_transfer\n");
|
|
t_reply("500","could not contact media server");
|
|
break;
|
|
}
|
|
break;
|
|
}
|
|
|
|
if (method == "INVITE") {
|
|
avp_write("sip:callme@example.com","$refer_to");
|
|
if (!t_write_unix("/tmp/sems_sock","announce_transfer/announce_transfer_headers")){
|
|
log("could not contact announce_transfer\n");
|
|
t_reply("500","could not contact media server");
|
|
break;
|
|
}
|
|
break;
|
|
}
|
|
|
|
if (!t_write_unix("/tmp/sems_sock","announce_transfer")){
|
|
log("could not contact announce_transfer\n");
|
|
t_reply("500","could not contact media server");
|
|
break;
