A customer has an UC520 with some ISDN BRI lines.

He routes the outbound calls by dial-peers across the BRI ports with different preferences.

When all ports are busy, is there any alert or something similar that could inform the calling party taht all lines are busy or in that moment there are not enough free ports in order to carry out the call?
