Re: [reSIProcate-users] cancel Client INVITE does not stop retransmitting

[Byron Campen <bcampen@xxxxxxxxxxxx>]

Hmm. Interesting. I'm going to have to mull this one over...

Best regards,

Byron Campen

I can't find anything explicit in the RFC for direction on this one.  I suppose though that it makes sense to stop re-transmitting the INVITE.  I'll look into this further.

Scott,

CancelClientInvite transaction msg dose not cause resip stack to send out CANCEL msg, but mark the transaction as bing abandoned. It should stop retransmitting INVITE msg.

My question is why resip stack keep retransmitting the canceled INVITE msg.

Thanks

Frank

A cancel cannot be sent out unless a 100 trying or provisional response has been received.  From section 9.1 of RFC3261:

"If no provisional response has been received, the CANCEL request MUST NOT be sent; rather, the client MUST wait for the arrival of a provisional response before sending the request."

Hi,

The resiprocate version is 1.4.1.
The call scenarios is  to send INVITE and send cancelClientInvite to stop retransmiting INVITE after 200 ms. There is no response from server.

But it did not stop it.
