*I tried sl_send_reply(), send_reply() and t_reply() (after t_newtran() for the last one).*

*all did not work.*

*if i send reply before the cancel arrives, yes, no problem.*

*but i want to reply to the cancel with 487, and it does not seem to work.*

*the only differences between my reply and the 487 destination's reply, is the to_tag and the Cseq method (Cseq number is the same).*

*the destination's 487 to_tag is similar to the 180/183 to_tag that it sent prior to canceling and the 487 Cseq method is for the INVITE.*

*on the reply i generate th Cseq method is CANCEL.*

*any ideas?*

*thanks,*

It should work to send the 487 with any To-tag, because the call is not answered yet and the proxy can do parallel/serial forking, where there are various tags anyhow and only one is picked up in normal case.

Have you tried to just send the 487 reply with send_reply()? Wasn't working?

Why would you want to do that? Curious.

I did however lack the capability of accessing the Kamailioi defined to-tag in the scripts. Maybe we should make it available in a pseudovariable somewhere.

/O

I have a need (unfortunately :-)) to suspend the 200ok answer that i s being relayed to the caller. I am using t_suspend() and t_continue() for it. But, when the caller decide to cancel the call before I managed to resume the transaction, I would like to send a 487 stateless in order for the client to disconnect immediately.

So, I need to send the 487 with the relevant to_tag.
