RE: DTMF Tone
Hi andy.buchan,

Could you upgrade the firmware to the latest version firstly and try again?
You can get the firmware from here.>>9.72.0.30<<
For how to upgrade the firmware,please refer this FAQ.

[FAQ]How to upgrade firmware?

1.Do you mean set a line key as DTMF?
2.Then A call B, B pick up.
3.And press the transfer button
4.Try press the DTMF button to transfer the call to the other extension. But it doesn't work?

Is it your scenario? If not, could you please describe the detailed operations?

thanks
