Hey Folks,

Is there a trick to getting an IP phone to connect both inside the office and from outside?
We have two MIPU, one on the internal network and one with a dedicated public IP.

Is it as simple as having the phone register to the MIPU with the public IP?

Cheers,

-B

Always registering to the external IP would be the simplest way. I don't remember if Toshiba phones accept a domain name rather than IP, but if so - the best way would be to use split DNS where the domain name resolves to the internal IP when on the LAN, and the external IP anywhere else.

Only IP addresses in the Toshiba IP phones. No DNS, domain names.
You can set 2 IP addresses in a phone, the primary and the secondary. What I have done is set the internal IP address to the primary, and the secondary IP address as the public WAN. When it fails on the primary, it will try the secondary IP address.

As mentioned, you can also just use the public WAN IP address for internal IP phones in most cases.
