RE: CP960 Skype for Business + Conference Dial in
Hi Patrick,

Thanks for your report and this is Michael from Yealink, nice to work for you.

For this issue, may I know which firmware you use ?

Normally it is because that the DTMF type you used is not recognized by the server side , so please kindly change it and double check again.

Web page path : Account->Advanced->DTMF Type

Configures the DTMF type for account X.
1-RFC 2833
3-RFC2833 + SIP INFO
If it is set to 0 (INBAND), DTMF digits are transmitted in the voice band.
If it is set to 1 (RFC 2833), DTMF digits are transmitted by RTP Events compliant to RFC 2833.
If it is set to 2 (SIP INFO), DTMF digits are transmitted by the SIP INFO messages.
If it is set to 3 (RFC2833 + SIP INFO), DTMF digits are transmitted by RTP Events compliant
to RFC 2833 and the SIP INFO messages.
X ranges from 1 to 16 (for SIP-T58V/T58A/T56A)
X is equal to 1 (for CP960)

Please test and if issue still not solved, please provide pcap file , bin file and level 6 log file for us for a double check , you can refer to below guide aobut how to get them :
