The internal SER timer hits and the request times out (the request is not terminated). See SER-GettingStarted doc at ONsip.org for a full example of call features like forwarding. g-) ----- Original Message ----- From: "zhangshuai" zhangshuai@goldentek.biz To: "serusers" serusers@lists.iptel.org Cc: "wuyuan" wuyuan@goldentek.biz Sent: Friday, February 10, 2006 11:18 AM Subject: [Serusers] a question about "cancel" in forwarding scenario

Dear All,

I want to make use of avpops module to achieve forward on-no-reply. When ua1 calls ua2 and ua2 is off-line, or busy, or doesn't answer the phone, the invite should be forwarded to ua3 and ua3 begins ringing.

In my tests, first, ua1 sends "cancel" when ua2 is ringing. Ua1 receives "487 Request Terminated" from SER. Second, ua1 sends "cancel" when ua3 is ringing. So, theoretically, ua1 should receive "487 Request Terminated" after "200 canceling" from SER, right? But, ua1 received "408 Request Timeout" instead. So strange. How come?

I think something is wrong with my ser.cfg. Could anyone help me about this? Thanks in advance.

Here is my ser.cfg:
