My mistake, the TVS50 will use both DPT/APT aka DPITS/APITS. However looking at the KX-TA624 manual it says it can only communicate with APITS which is the same as the KX-TA824 now referred to as APT.
From the KX-TA624 user manual: Voice Mail Integration ( Option) has been upgraded to APT Integration. In addition to standard services (Custom Service, Automated Attendant Service, Voice Mail Service, Interview Service) for outside callers, proprietary telephone users can take advantage of: Live Call Screening you can monitor incoming calls like you would with a telephone answering machine. Take the call or let the caller leave a message. Two-Way Recording you can record conversations into your mailbox or someone elses mailbox. Voice Mail Transfer you can easily transfer a caller to a mailbox. LCS Cancel Two-Way Record Two-Way Transfer Voice Mail Transfer DSS One-Touch Dialing Available when the KX-TA624 is connected to a Proprietary Telephone capable Panasonic Voice Processing System (one that supports APT Integration; KX-TVS50/KX-TVS80). There is no mention of the KX-TA624 supporting DPITS aka DPT, only APT Donald R.
