Hi Everyone! In some call scenario I have incoming 180/SDP. And SDP contains this line: ..... a=rtpmap:101 TELEPHONE-EVENT/8000 .....
My gateway cannot parse this string "TELEPHONE-EVENT/8000" because upper-case letters are used. If "telephone-event/8000" string comes in lower-case letters only, then it's fine. Value of "a=" field can be parsed. So the question is: Is it allowed to use upper-case letters for "TELEPHONE-EVENT"? I was searching through RFC, but could not find the explicit approval. RFC4566 says "An SDP session description consists of a number of lines of text of the form: <type>=<value> where <type> MUST be exactly one case-significant character and <value> is structured text whose format depends on <type>. In general, <value> is either a number of fields delimited by a single space character or a free format string, and is case-significant unless a specific field defines otherwise. Whitespace MUST NOT be used on either side of the "=" sign." I found that <type> fied should becase sensitive. Bot how about <value>?
