We have a new sales rep working out of his home office. Is there a way to connect a cisco phone from that location without having to also establish a VPN tunnel.
i.e. just point the phone at the UC520 and set his firewall to forward specific ports to the phone?
If it can be done.
1) What security settings do we have to change on the UC520 to allow that specific phone to connect from an outside address?
2) What ports do we need to forward on his side?
