It seems that there are APCO P25 emergency functions and there are ASTRO P25 proprietary extensions.. The Harris infrastructure deals with the APCO 25 parts... but seems like ASTRO 25 radios do not exactly. We are finding a few issues like this here as we have an 800 Harris-P25 system, and while the XTS radios do work on it, their firmware does react differently as ASTRO P25 is not exactly APCO P25...
There is a check box in the ASTRO 25 RSS for disabling non proprietary features, it may help....I have tried both ways and the emergency clearing issue is definitely a questionable compliance issue in ASTRO P25 being APCO P25... I hope the compliance lab testing gets it squared away as to who needs to fix it....There is also a busy channel lockout type hang on PTT attempts on ASTRO25 radios too... when we are in message trunking ( channel assigned per PTT ) mode... the XTS's are blocked from PTT for a longer than optimum time..
