[OpenSIPS-Users] HTTP to SIP

[Bogdan-Andrei Iancu]

Hi Remi,

the simplest way is to build a CGI do deal with the http part - this CGI 
can simply invoke via XMLRPC the t_uac_dlg command from opensips, tm 
module (see 
http://www.opensips.org/html/docs/modules/1.6.x/tm.html#id272728) - with 
this command you can make opensips to generate a SIP request.

For how to use this IM command, see the example file locate under 
examples/web_im/send_im.php in SVN/tarball

So basic schema:
    browser ---> HTTP ---> WEB server (CGI) ---->XMLRPC ----> OpenSIPs 
---->SIP  ----> MESSAGE

Regards,
Bogdan
