PRI Config problem

[baban_ele_DUP]

Hi all,
I have Two PRI from different service providers(suppose A and B)
I have connected both in OXO System (Rel 6.1),
programmed like this:
DID modification table 1 xxxx-41 (A PRI)
2 xxxx-42 (B PRI)
Public No Plan 41500 41699 500 (500 is extn series)
42500 42699 500 ( ,, )

Istallation No. is blank


Now DID/DOD works for only one(for A) PRI. For second PRI (for B) only DID works.

Can be programmed oxo to use the both PRI's DID along with DOD?

There are two ways to make this work as I can see:
1: Other labels: DDIMnused has to be set to 01 in ordrer to use DDI modification table.
or
2: Try with the full public number in Public Numbering Plan and blank installation number.
