	When OPUS codec is used, DTMF digit is always doubled keyed, so IVR like conference bridge can't accept it. If G.711 or G.722 codec is used, there is no this kind of issue. DTMF can pass correctly.

	Thanks for reporting. My problem is, that I can't test with Opus because all my providers don't support Opus codec. Do you know any test number that I can call using Opus and send DTMF to?

	I am using it with Genesys PureCloud Edge, which works like Cisco CME. The Edge uses G.711 code with service provider SIP trunk, and can use OPUS codec to communicate with SIP endpoints. The Edge does transcoding. The Edge is in a private network, so there is no way to provide you the access to Edge. Sorry about it.
