cSipMediaStreamDtmfPayloadType
Module: CISCO-SIP-CALLS-MIB
OID (symbolic): CISCO-SIP-CALLS-MIB::cSipMediaStreamDtmfPayloadType
OID (numeric): 1.3.6.1.4.1.9.9.995.1.1.4.1.8
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The RTP payload type of the negotiated DTMF-relay. RTP payload specifies the data transported by RTP in a packet, for example audio samples or compressed video data. A value of -1 means that no codec has been negotiated. RFC 3551 specifies the payload type number to be used with different codecs. The following are some of the standard payload types applicable to SIP calls :
PT Encoding Name 0 PCMU(G711ulaw) 3 GSM 4 G723 8 PCMA(G711alaw) 9 G722 15 G728 18 G729 96--127 dynamic
For other codecs, dynamic payload types in the range 96--127 are negotiated during call setup. Also note that Cisco has preassigned certain payload types in this dynamic range for certain encodings:
PT Function 96 fax 97 fax-ack 100 NSE 101 NTE 121 DTMF-relay 122 Fax-relay 123 CAS 125 ClearChan
What is cSipMediaStreamDtmfPayloadType?
Reports the RTP payload type number negotiated for carrying DTMF-relay tones in a SIP media stream, with -1 indicating that no DTMF codec has been negotiated.
