Installation
IP 705 Manual 17
If the phone successfully passes through these stages, the phone
shows the time and extension in the LCD screen and is now in normal
operating mode.
If it doesn’t pass through these stages successfully, refer to
“Troubleshooting” on page 43.
Remote Installation
To install the IP 705 phone at a remote location, using a broadband
connection with or without a router:
1. In the firewall at the corporate network, open TCP/UDP ports
required by the IP 705. (For a listing of these ports, refer to “Firewall
Considerations” on page 42.)
2. Check the AltiWare server’s IP extension settings. Make sure
Dynamic IP Address is checked, enough physical extension licenses
are available, and that the proper codec setting is configured.
3. If DHCP is not used, configure the phone’s local IP address and
Gateway IP address. (Depending on the Internet Service Provider’s
recommendations, you may or may not want to use DHCP.)
a. Press the Menu button, scroll to NETWORK, and press the Enter
button.
b. Scroll to LOCAL ADDRESS, then press Enter.
c. Enter the IP address, using the * key to input periods, then press
Enter.
4. If the IP phone is behind a NAT router, return to the NETWORK menu
and set the ENABLE NAT setting to YES.
5. If the IP phone is behind a NAT router, configure the router’s DMZ
to point to the private IP address of the IP phone.
6. If AltiServ is behind a NAT router, configure the router to forward the
following ports to AltiServ’s private IP address:
• TCP port 10032 (for phone service)
• TCP port 1720 (for H.225)
