Changeset 3938 for pjproject/trunk/pjsip/src/pjsua-lib/pjsua_core.c

Message:

Fixes #1442: Unable to make call if disabled media is included

Add an API pjsua_schedule_timer2() to allow application to schedule a callback function to be executed after a specified time interval. This enables app to post a delayed job which, in this case, allows the initialization of all media transport creations to finish first before we get the media transport creations result.
