IP Phones under two different numbers reachable?

[ThomasLiss]

Hi all,

I am wondering if it is possible to have IP Phones reachable under two different numbers. Our router (1760) is equipped with two ISDN interfaces. One connects to the internal pbx and one directly to NTBAs to call outside.

When calling internally from the pbx to ip phones, the numbers of the ip phones should be 123456-1010 to 123456-1059. When calling ip phones from outside, the numbers should be 987654-0 to 987654-79.
Is this somehow configurable on the router or CallManager?

Thanks,

Thomas Liss

You could setup shared lines on your ccm. this way 1 phone will have to dn's, line 1 will be the pbx dn, line 2 will be the ddi.
