Hello, I have a uc560 with around 30 phones deployed across the network inside a dedicated VLAN.
Now I have a few phones that I cannot deploy into the Voice VLAN because they are connected to non-manageable switches, so I must deploy them at different Data networks (not uc560 data network). To do that I configure phones settings with static IP, mask, router and TFTP server.
All networks are routed between them with a firewall.
The problem is that I cannot get this phones registered at uc560.
I verified that I can reach uc560 from different networks with ping and ssh.
I also verified that I can reach the phone with web access and ping from the uc560 data network.
Finally I tried a first firewall rule ALL to ALL.
Network connectivity between the phone and uc560 across networks seems to be right, but the phones doesn't register at uc560.
What can I do?
