Message:

Fixed #1170 (Assertion when receiving updated SDP offer with all media lines removed):

• pjsua_media.c checks if audio media is present in the offer; if not, do not set any answer
• sip_inv.c checks if app has supplied an answer after on_rx_offer() callback is called, and returnd 488 (Not Acceptable) if not (previously, it will return 200/OK without SDP!)
• added a SIPp scenario file to reproduce this
