Configuration File Parameters (continued)
Description
Whether the phone can do local call forwarding. This is a boolean
field; it is either enabled or disabled.
Valid values are 0 (disable) and 1 (enable). Default is 1.
(Optional) Location of the company logo file. This logo appears on
the phone display. The background space allocated for the image is
90 x 56 pixels. Images that are larger than this will automatically be
scaled down to 90 x 56 pixels. The recommended file size for the
image is from 5 to 15 Kb. For example, use logo_url:
"http://10.10.10.10/companylogo.bmp".
Note
(Optional) Configures the voice-mail number that is dialed when the
messages button is pressed. Value is typically a phone number but
can be a URI.
(Optional) Displays the message waiting status.
Note
(Optional) WAN IP address of the Network Address Translation
(NAT) or firewall server. Value is either a dotted IP address or a
DNS name.
(Optional) Enables NAT.
Valid values are 0 (disable) and 1 (enable). Default is 0.

This parameter supports Windows 256 color bitmap format
only. CMXML PhoneImage objects are not supported for
this parameter. Using anything other than a Windows
bitmap (.bmp) file can cause unpredictable results.
You cannot set this parameter in the configuration file.
If NAT is enabled, the Contact header appears as follows:
Contact: sip:lineN_name@nat_address:voip_control_port
If the nat_address is invalid or UNPROVISIONED, the Contact
header appears as follows:
Contact:
sip:lineN_name@phone_ip_address:voip_control_port
and the Via header appears as follows:
Via: SIP/2.0/UDP phone_ip_address:voip_control_port
If NAT is enabled, the Session Description Protocol (SDP)
message uses the nat_address and an RTP port between the
start_media_port and the end_media_port range in the C and M
fields. All RTP traffic is sourced from the port advertised in the
SDP message.
