asterisk users - Dec 2004 - ftmp header

All,

	We are using a SIP provider that is expecting 0-15 response for
fmtp. Our CVS Head asterisk server is sending 0-16, I looked up an rfc
and it stated:


RTP Payloads for Telephone Signal Events
    RFC 2833
    Henning Schulzrinne, Scott Petrack.
    May 2000

    Implementation notes:

        * Implementations can support events 0 through 15 (DTMF) by
simply ignoring the packets, but MUST declare all event numbers that are
meaningful to it in the fmtp parameter, including 0 through 15


Any ideas? 
Thanks!

How about opening a bug? 

Here's what I see in the source:
/* Indicate we support DTMF...  Not sure about 16, but MSN supports it 
so dang it, we will too... */
                                  snprintf(costr, sizeof costr, 
"a=fmtp:%d 0-16\r\n",
