These two functions require sip:

prefix.

Content-type of the segments sometimes miss space after the column
Content-Type:application/sdp\r\n
therefore the line 400
const ct = /Content-Type:\s+(.*)\r\n/.exec(segments[i]) ;
does not extract type. The fix is to allow 0 or more \s like
const ct = /Content-Type:\s*(.*)\r\n/.exec(segments[i]) ;
By https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html, the boundary starts with \r\n-- and following \r\n\ belongs to the segment:
delimiter := CRLF "--" boundary ; taken from Content-Type
field.
; when content-type is
multipart
; There must be no space
; between "--" and boundary.
the regex in parseUri assumes host names will be in dot decimal format
