So how many numbers or entries can I block?PianoGuy wrote: ↑There is no such thing as an OBi101.
The OBi2 series has a new feature, X_BlockedCallers. Practically, I think it's relatively pointless, as it only allows you to block a maximum of 10 numbers. So, don't let this sway your decision on which device to purchase - if you need the 110's FXO port or you like the price of the 100, go for it.
The User Defined Digit Maps feature on the other hand has a maximum length of 511 characters which should allow you to block about 42 numbers per DigitMap. This feature is the same on both OBi1 and OBi2 ATAs.
How many digitmaps are there?
