I'm also running mobian bookworm Phosh on my PP, but it doesn't have a SIM. But it can make SIP calls. However, I can't bring up the dialpad after starting or answering a SIP call.
My Librem 5 running Byzantium Phosh has an active SIM and it sends a short tone for dialpad tap. A long press does nothing until release, when it sends a short tone. (This is during a call to a landline on spreaker, so I hear what comes from the L5.)
I suspect the Phosh dialpad sends fixed length (short) tones and only afer release.
