Re: [Kamailio-Users] [SR-Users] force_rtp_proxy() vis-a-vis BYE

no. The script needs just rtpproxy_session_init(). All the rest is done automatically in the module. Inside a module, you can register functions that are executed before executing the configuration file for each sip message. So, here is what is needed: - registers callback functions for pre-script event for reply and request - if it is an initial invite, then skip processing in the callback - if it is a reply or a in-dialog request, search for Record-Route/Route headers matching "myself" - if the R-R/R headers have "nat=xyz", then process rtpproxy_session_update() - export to config file the function rtpproxy_session_init() that has to be called for initial invite and append to R-R the parameter "nat=xyz" (this should be configurable) In the config file, just call rtpproxy_session_init() and that is. Probably this function needs some flags as parameter to control the behaviour, flags that could be added as value to nat parameter, if needed later.
