I just installed CER7.0 in the LAB (beginner) and have problem to setup IP Subnet based.
-created two ERL. total three ERL includes 'default'
-switch based ERL is works okay. able to pick proper ERL
-I assigned IP Subnet to new created ERL but always pick 'default' ERL
-when I click Phone icon on the 'IP Subnet' ERL membership, I got 'No match found' result.
-I used 'IP Subnet' value to the IP address show in CUCM device registration (subnet part)
