Hello:
I need some help with getting an unanswered call rolled over to
SEMS for voicemail.
When an inbound call goes unanswered I would like to call to
go to SEMS voicemail. The SEMS/SER interface works for
specific test cases but the general case is failing with the error
"parse error (700,18-19): Command cannot be used in the block".
In the general case I have a voicemail check in the main section of my
config file. If the calling party enters a specific extension the call
is routed to
SEMS using the logic: (This works).
## test
if (uri=~"^sip:68001")
{
if(method=="ACK" || method=="INVITE" ||
method=="BYE" ||
method=="REFER"){
if(t_newtran()){
if(!vm("/tmp/am_fifo","voicemail")) {
log("couldn't contact voicemail server\n");
t_reply("500", "couldn not contact voicemail server");
};
}
else {
log("could not create new transaction\n");
sl_send_reply("500","could not create new transaction");
};
}; # end if method
break;
};
## end test
For the specific case I moved some of the above logic into a
failure_route block, I added the following check for this failure
condition in the main config file and then I attempt to execute
the voice mail logic in the failure block. I don't think the t_newtran
function can be used in a failure block but I don't see how else
to implement a "roll over to voicemail when not answered" type
of routing.
My failure check code is:
# redirect user to vm if not availabile? Flag it now in case of
# rewrite and store it in flag 6 for route block 6
if (is_user_in("Request-URI", "voicemail")) {
t_on_failure("6");
setflag(6);
log(1, "[SER]: Flag for VM redirect successful. \n");
} else {
log(1, "[SER]: Flag for VM redirect unsuccessful. \n");
};
My failure_route is:
failure_route[6] {
xlog("L_INFO", "\n[SER]: START FAILURE BLOCK #6 Unavailable user:
Time: [%Tf] Method: <%rm> R-uri: <%ru> Contact Header: <%ct>
From uri <%fu> To < %tu> IP source address <%is> \n\n");
if(method=="ACK" || method=="INVITE" || method=="BYE" ||
method=="REFER"){
if(t_newtran()){
if(!vm("/tmp/am_fifo","voicemail")) {
log("couldn't contact voicemail server\n");
t_reply("500", "couldn not contact voicemail server");
};
}
else {
log("could not create new transaction\n");
sl_send_reply("500","could not create new transaction");
};
}; # end if method
break;
}
Any thoughts on this would be helpful.
Thanks,Steve
