[asterisk-dev] chan_sip.c / sip.conf : need similar option as "promiscredir" but for REFER and not redirect (302)

[tloginbr-asteriskdev at yahoo.com.br]

Hi guys, sorry if this is the wrong list, but I've tried the users
list and forums already, so maybe I'll need to change some code to
get what I need. I need to enable my asterisk (1.4.18.1 running on
debian etch) to accept REFER commands to non local sip address. I've
tried all sorts of configurations inside sip.conf but it always tries
sending my call to a local extension. The scenario is liker this: I
get a call from PSTN and dial a sip address (not in the same machine
as asterisk) that has one sip application (not asterisk). This
application will transfer the call to a second sip address (not
asterisk either) depending on user input. So I need asterisk to
receive the REFER command from my first application and blind
transfer the call to my second application. The problem is that it
always tries sending the call to a local extension. Bellow is a sip
debug from the sip messages. My first application is running on
"sip:5080 at 201.73.67.7:5080" and my second application is running in
"sip:5070 at 201.73.67.7:5070". There many different possible addresses
like this second application and they change, as I load more
application when its needed, so its not really an option to create
extensions for each of this addresses and register them in the
asterisk box. In different part of this system I use redirects (302)
ans the option "promiscredir=yes" inside sip.conf did the job for me,
but in this case I need something to work with REFER.

Thanks for all help,

Thiago
