Re: [OpenSER-Users] Avoid Loops between Openser and 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); }
