8 Adding Handsets
8.1
SIP Phones
8.1.1 Plug-and-Play
Allworx phones can be added to the system using plug-and-play installation. Once the network connection to
the server is set up, the phones will register with the server the next time they reboot or power up. VoIP
phones from other manufacturers can be manually added. See Section 8.1.3.2, Generic Phones.
Depending on the DHCP configuration on the site’s LAN, some network configuration of the phone may be
required:
1. If the phone is getting its IP address from the Allworx
server’s DHCP server, the phone needs no
manual configuration.
2. If the phone is getting its IP address from a non-Allworx
server’s DHCP server and the DHCP server
sends the phone the Allworx
server’s IP address as the TFTP boot server (option #66), the phone needs
no manual configuration.
3. If the phone is getting its IP address from a non-Allworx
server’s DHCP server and the DHCP server
doesn’t send option #66 to the phone, then the Allworx
server’s IP address needs to be manually set on
the phone as its boot server. See the Allworx Phone Guide for more information.
4. If the DHCP server is sending the wrong (or no) option #66 IP address:
• For Allworx IP phones, the manual setting on the phone will override the value sent by the DHCP
server.
• For Cisco phones, the alternate TFTP server should be set on the phone to override the value sent
by the DHCP server.
5. If there is no DHCP server, then the phone needs to be manually configured with a static IP address, a
netmask, a gateway and an Allworx
server’s IP address as its boot server.
TIP: If you are having difficulty configuring a phone, restore it to factory defaults and reapply the desired
settings.
When an Allworx
IP phone is booted on the network, if a new version of phone software is available, the
phone will ask if you would like to load the upgrade.
When a plug-and-play phone is registered with the server, it will appear on the Phone System / Handsets
page in the SIP Handsets section. It will show the correct model and the MAC address will be displayed in
the Identification column.
An Allworx IP phone can be assigned to a user or replace an existing phone when it is first connected to the
Allworx system. The following options are available:
• Assign a user to the phone (NOW / ADD). Select from the list of all system users or limit the list to
those users with no phones assigned. Reboot the phone to complete the user assignment.
