Chapter 17: AltiGen IP Phone Configuration
218 MAXCS ACC 6.7.1 Administration Manual
After setting parameters on the General tab, go to the tab that corresponds to the
phone type, and configure the programmable keys (plus the Display Workgroup
Status field on the Alti-IP 600 and IP 705). Programmable key settings are described in
the next table.
TFTP
Lets you assign the TFTP server to which the IP phone can connect for
updating firmware when necessary. Enter the IP address of the TFTP server
in the Server field.
To reset the phone and download the latest firmware image, check the
Reset IP Phone and Boot Download check boxes. If you only check the Boot
Download box, the firmware will be downloaded when the IP phone reboots
(power cycles) next time.
Note: Make sure the TFTP server is running and the new firmware image
is loaded to the correct directory before you reset and download firmware.
NAT Setting
This setting is for a remote IP phone with a private address and behind
NAT. When connecting to the AltiGen system, the system will use this
information to execute the NAT traversal for the IP phone. The NAT status
and address are read-only fields.
• NAT Status – Indicates if the IP phone is behind a NAT router. Read
only.
• NAT Address – This is the NAT router’s public IP address, as set in the
Extension Configuration window. Read only.
Registry Keep-Alive Duration – Indicates how often a SIP registra-
tion message is sent to the server when the IP phone is behind a NAT
router. You need to enter a Diagnostic password when logging in to
MaxAdmin (before you enter your Admin password) to enable this con
-
figuration. Default setting is 60 seconds.
3rd Party SIP
Device
Enable SIP Telephony Service – Enables SIP hold, SIP transfer, and SIP
server-side conference features for the selected 3rd party IP phone
extension.
If the IP phone is SIP-enabled, the Flash key (which includes the Hold
button in MaxAgent/MaxCommunicator) is not supported when you check
this setting.
Network
Setting
• TOS(Hex) – Type of Service. 8 bits in the IP header are reserved for
the service type. They can be divided into 5 subfields: The 3 precedence
bits have a value from 0 to 7 and are used to indicate the importance of
a datagram. Default is 0 (higher is better). Bits 3 4 5 represent the
following:
D: requests low delay
T: requests high throughput
R: requests high reliability
• Enable VLAN – If your network administrator has configured VLAN,
check this check box to enable VLAN for the selected phone. Then enter
the VLAN ID for the line port (voice service) and the VLAN ID for the PC
port (data service). (Get these IDs from your network administrator.)
See
“Virtual LANs” on page 299 for information on VLANs.
