Summary:                    [patch] Session failure with specific SDP-Content
(one media specific c= line, no session specific c= line)
Description: 
I try to setup a fax call with provider sipcall.ch. The provider equipment
(CISCO according to SIP-message) sends back a T38 ReINVITE. This ReINVITE
contains a sdp-message with no c= line in front of the first m= line. But
there was a media specifc c= line later in SDP.
In this case asterisk shows a warning "Insufficient information in SDP"
and quits the reinvite with "488 not applicable here".
As far as I understand the RFCs asterisk should handle this case (As it
did in 1.4.26.2)
