I'm implemeting 'site code' between sites and get a problem the IP phone 'presence' status to other site's
IP phone has 4-digits extension and use 'site code' to dial another location and the 6-digits telephone number updated into AD (CCM LDAP sync from AD)
1. IP Phone 'presence' from directory 'placed call' when dial from '81' site-code area
-dial 812001, the IP phone shows 'idle'
-dial 822001, the IP Phone shows 'unknown'
2. Attendant Console. added IP phones from siteA and siteB but both IP phone status are 'unknown'
How to get updated the IP phone 'presence' status which implemeting 'site code'?
Thanks in advance,
