Dave, Of course Voice Alert is not digipeated. However, one would not 
hear the Voice Alert if it was out of simplex range, therefore if you 
hear it, you generally  can work it. You do not need to see "who" 
actually broadcasted the voice alert, just briefly ask who is on 144.390 
Voice alert. The other station will hear you and respond and tell you 
what voice channel he is on, then you both QSY.. No harm what-so-ever to 
the aprs frequency for that brief mobile to mobile exchange..
