[asterisk-r2] mfcr2_max_dnis is also the minimum dnis length acceptable?

Hi

I have an Elastix with the following setup

elastix*CLI> mfcr2 show version
OpenR2 version: 1.1.0, revision: exported

and this is my problem. If I set mfcr2_max_dnis to a length greater than the
number of digits passed by the NortelPbx, I got this error

but when I set the mfcr2_max_dnis to the length of number of digits passed
by NortelPbx, the call can get through.

Is there something I need to set to make this thing work, so that when the
number of digits passed is between 14 to 18 in length it will be handle by
openR2 without an error?

Thanks
