Parameter Description
Web/EMS: RFC 2833 Payload
Type
[RFC2833PayloadType]
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.
Notes:
 Certain vendors (e.g., Cisco) use payload type 101 for RFC
2833.
 When RFC 2833 payload type (PT) negotiation is used (the
parameter TxDTMFOption is set to 4), this payload type is
used for the received DTMF packets. If negotiation isn't used,
this payload type is used for receive and for transmit.
