New Revision: 400361

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=400361
Log:
Fix crashes in res_pjsip_sdp_rtp and res_pjsip_t38 when a stream is rejected and external_media_address is set.

The callback function for changing the media address in streams wrongly assumes that a connection line
will always be present. This is false as no line is present if a stream has been rejected.

(closes issue ASTERISK-22645)
