Just installed a KX-T7765, connected to he DPH4 card, TDE100. When the doorphone rings the destination, after x number rings it rolls to voicemail. How can I block the doorphone from going to voicemail, ie just ring x number of times and drop?

Second question, when I try to configure the door relay, I get an error message that the hardware is not installed. I thought the DPH4 (KX-TDA0161) supports doorphones and door relays on the same card.

I just setup the doorphone destination as an ICD with the extension, since the ICD doesn;t have VM configured, the doorphone rings only.
