Re: [Serusers] Error forwarding calls to Voicemail from SER

Girish I have just followed your advise and it works perfect now, ser accounting module reports "Sip-Response-Code=487" and no "invite" goes to asterisk again, ...thank you very much for your invaluable help .

Rafael,

As i said in my previous mail, it just was a guess. Can you try modifying your route[1] something like this. I think this will send only the unanswered calls to voicemail. All other 4** status will be ignored. I havent tested it though.

Also, you were right. It is route[1], not route[4].

route[1] {

if (t_check_status("408")){ revert_uri(); rewritehostport("200.110.2.132:5060"); append_branch(); t_relay (); break; }

}

Good Luck,

hello Girish I did some test using t_check_status ("487") in failure_route[1] like this:

failure_route[1] { if (t_check_status("487")){ revert_uri (); rewritehostport ("200.110.2.132:5060"); append_branch(); t_relay_to_udp("200.110.2.132", "5060"); }

...but did not work, can you send us more details about how to use t_check_status("487") in route[4]?

thanks rafael

Hello,

Just a guess.. Can you add t_check_status (487) in your route[4] and see if the INVITE goes to Asterisk after cancelling?

Hello I have to insist in this issue since I´ve done several test using Sems and asterisk with very simple configuration files including the original example from ser-cvs... in brief: if I call to a user who belongs to voicemail group and I cancel the call before VM forward routine begin then an "invite" is sent to a voicemail server generating and sending a file with No audio, and I cant account this call with "Sip-Response-Code=487" (just an start record without stop)...

does someone know how to solve this problem????

thanks in advance

Rafael
