Thank u. I install twinkle in Ubuntu Linux, but Unfortunately, failed 
to. Says "403
Forbidden" from web output.

My call environment is:
* openser: 192.168.35.40: 5060
* A: Twinkle 1.1 : 192.168.35.40: 5090: 8841
* B: eyebeam 1.5.16.1: 192.168.35.114: 8831
* C: eyebeam 1.5.16.1: 192.168.35.253: 8851

Test call process is:
1. A call C, C answer, get 200 OK, and RTP media begins
2. use click_to_dial.php to send REFER to A, REFER-TO B
3. A reply "200 OK 403 Forbidden"

U can open the cap file in attachment.

Where is wrong?
