[asterisk-dev] How to send SIP replies to another Asterisk?

[Hauke Joachim Zuehl]

Hello all :)

I have two Asterisk servers at two different locations. A routes to B
and if A has a problem to do a call it sends a reply back.
The point is that I want to create own SIP messages like "603 No route
to UA". Asterisk B then reacts somehow to this message (and maybe sends
a BUSY back to the callee's UA).

I found in SER the function sl_send_reply which is the function I am
looking for in Asterisk. But I don't want to use SER :)

So it will be nice if someone gives me hint (if necessary I will write
the code on my own and post it to Mantis as a patch).

Kind regards,
Hauke
