According to the IANA payload types: http://www.iana.org/assignments/rtp-parameters 96-127 are dynamic. Anything is available to use them. The "limitations" you are describing come from Audiocodes. In my experience with a wide variety of endpoints 101 is fairly typical/standard for RFC 2833. On Fri, Apr 29, 2011 at 11:00 AM, Boris Kovalenko <boris@tagnet.ru> wrote:

Ok. And why FS uses 101 while valid are 96 to 99? Or this means valid only for MP-118?
You don't have to change it. SDP will handle it for you.
I've worked with many AudioCodes gateways without every change the RFC2833 payload type.

In the Audiocodecs MP-118 User's Manual "The RFC 2833 DTMF relay dynamic payload type. The valid range is 96 to 99, and 106 to 127. The default is 96. The 100, 102 to 105 range is allocated for proprietary usage." But FS uses 101 by default. Is this ok or should I change it to 96 for example?
