asterisk users - Feb 2005 - DTMF Payload Type Compatability

We are having problems with DTMF generation with our supplier of IP to
PSTN call termination. Their (Entice) soft switch is looking for RFC2833
payload type of 99 but Asterisk is using RFC2833 payload type 101.

We are specifically having problems being able to access IVR menus and
voice-mail.

Does anyone have any ideas on how we can change the RFC2833 payload type
to 99 so we can work with their soft switch?

The Entice soft switch uses SIP

>From a quick glance at RFC2833, it looks like the payload type is
chosen dynamically. How is it announced by the peer? (use "sip debug")
