If the INVITE comes in from Asterisk, OpenSER replies with 480 and lets
Asterisk deal with sending call to voicemail (e.g. dialstatus =
unavailable). This eliminates the loop because the INVITE does not come back
to Asterisk.

Here is how I solve this.
In Asterisk, I add a SIP header just before sending it to OpenSER using
the
function: SipAddHeader(P-hint: From Asterisk).
Then, in OpenSER I have the following:
# check to see if user is online
if (!lookup("location")) {
# SIP from Asterisk or not a call attempt
if (search("(P-hint):.From Asterisk") ||
!(method==INVITE)) { sl_send_reply("480","User Temporarily
Unavailable");
exit;
} else {
route(2);
exit;
};
};
route[2] {
# Let Asterisk deal with voicemail/forward
sl_send_reply("181", "Forward to Voicemail");
prefix("vm");
setflag(9); # forward to Asterisk
route(1);
}
I can't understand why that should work, in fact Asterisk is receiving the
same INVITE he sent (well, RURI modified but the Asterisk bug is that it
doesn't recogniza a spiral).
