For many IP phones or adaptors, your Mac and telephone device must be able to find each other
at a known IP address. Many LANs are configured using DHCP which means devices may be
assigned IP addresses on a first come first served basis. Your configuration will be more stable if
the local IP address of your VoIP phone or adaptor and the host computer running Phone Amego
do not change. Many DHCP servers provide a mechanism to assign a static or fixed IP address to
a specific device which you can use. If you have an AirPort Base Station for example, launch the
"AirPort Utility", press "Manual Setup", and navigate to "Internet -> DHCP". I use a "DHCP
Beginning Address" of .8 to leave a few fixed addresses for other devices. In the "DHCP
Reservations" section below I then list the fixed IP addresses I have assigned along with their
descriptions.
Even if you cannot configure a static IP address, your VoIP phone or adaptor will normally be left
on all the time (24 x 7), so the DHCP lease should be renewed (keeping the same IP address)
before it expires. In the event of a power disruption, DHCP Servers are designed to remember
your previous IP address assignment and give it back to you unless it's not available. Finally,
Phone Amego can scan the first 255 addresses of the assigned IP subnet to look for your adaptor
and fill in the IP address automatically. If you notice your VoIP device is no longer "connected
and ready", simply press the Attach Device button and Phone Amego will try to find it.
To force Phone Amego to rescan for your device, delete the previous IP address (if any) and press
Scan.
