Changeset 4071 for pjproject/trunk/pjsip/src/pjsua-lib/pjsua_call.c

Timestamp:

Message:

Fix #1423:

• Added provisional media in call for generating initial and subsequent SDP offer/answer. If a reoffer is rejected by peer, the main call media will remain unchanged and the provisional media will be cleaned up (the cleanup is currently delayed until call gets destroyed or another reoffer/answer occurs).
• Reenabled media transport dump in pjsua_core.c.
