The distributor is in res/res_pjsip/pjsip_distributor.c, the distributor function being the entry point. That function returning PJ_TRUE indicates to PJSIP that it has been handled and no subsequent modules should be called by that running thread. The distributor itself, though, ends up executing things further in a worker thread using the distribute function. -- Joshua Colp Digium, Inc. | Senior Software Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - US Check us out at: www.digium.com & www.asterisk.org -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
