Remote Phones; Testing Ip Phones; Supported Ip Phones - Dell Fonality Installation Manual

4.2 Remote Phones
Your Fonality system supports remote IP phones that work and act exactly like phones on the LAN.
However, before you start using your IP phones remotely, you must first plug in the phones on the
same LAN as your Fonality Phone System so they can download their configuration files.
Fonality recommends that you place your Fonality Phone System on your firewall's DMZ port either
physically or via an administrative setting within your firewall. Registering remote phones with
your Fonality system requires the following changes:
1. The Server Address on the phone must be changed from sNNNN.pbx.fonality.com to
sNNNNx.pbx.fonality.com.
2. The following ports must be opened if your Fonality Phone System sits behind a firewall:
a. UDP 5060 (for registration)
b. UDP 10000‐20000 (for RTP audio)
Detailed instructions for each type of supported IP phone can be found at:

4.3 Testing IP Phones
Verify that each phone can communicate with the Fonality Phone System by lifting the handset and
dialing "0". You should hear the default auto attendant greeting. This is the same greeting your
callers will hear when your Fonality Phone System answers incoming calls. You can see the status of
each IP phone using the Extensions tab in the Fonality Admin Panel. View the IP address of each
registered phone by "mousing‐over" the pulsing, green icon. If the icon is flashing red, the phone
will not be able to place or receive calls.
4.4 Supported IP Phones
The Fonality Phone System only supports IP phones qualified by Fonality and sold by Dell. You
cannot provision "used" or "new" IP phones or phones from a previous phone system or another
vendor. This limitation exists in order to ensure compatibility today and for all future upgrades to
the Fonality Phone System.
