Solved: Cannot register with a different sunbet than the UC560 one.

Hi,

On my architecture, we have the uc560 on a Vlan and a subnet : 192.168.x.x | vlanx

all the phones on the same subnet are able to register.

The problem is that on an other subnet, 192.168.y.x tagged in the same voice Vlan, the phones are not able to register.

All firewall rules on my ISA permit communications beetween those network. I am able to ping all phones in 192.168.x.x from 192.168.y.x but the UC560 is rejected all communications from others network. I disable all firewall and ACL rules from the UC using CCA but nothink to do.

Is someone able to help ?

Regards,

Since you mentioned having an ISA500 firewall, you will likely need to setup static routes in the UC500 for the other ip subnets pointing to the ISA500. In addition, please ensure all routes are in the ISA500 pointing to the UC500 subnets at the UC500 router address. You should be able to ping everything in all directions to ensure routing is working.
