SP800 DTMF not possible

[reamen]

We are currently using the following configuration for a customer:

3CX Hosted V20
Snom SP800
Azure Virtual Desktop
3CX Softphone in Azure for CTI control of the Snom SP800

Unfortunately, in this configuration, the keyboard for DTMF does not appear during a call. Therefore, it is not supported. Is there a way to enable this?

Snom Firmware is 10.1.215.13
3CX Firmware is Version 20.0 Update 9 (Build 995 Release - AI 1.4.48)
No Beta Firmware

One Snom is the Router phone and the other use this snom as sbc

Is the Firmware Update 10 Beta work with DTMF?

Hi,

There is no way to enable this.

Even from the device's own web UI, there is no way to send DTMF during an active call.
