I know that this can sound weird, but the question is.
I have to create a h.323 trunk between two CCM.
Is it possible to use the same route pattern ex : 6xxx on both side of the trunk ( exemple if there is 6xxx extension on both system.
Yes, just make sure the inbound CSS from the ICT doesn't reach the 6XXXX partition, otherwise it would loop.
The ICT should only be able to reach the DNs you want via CSS and partitions
