GXP17xx Administration Guide
Note:
This parameter must be set to "No" for Direct IP Calling to work.
Keep-alive Interval
Specifies how often the phone sends a blank UDP packet to the SIP server in
order to keep the "ping hole" on the NAT router to open. The default setting is 20
seconds.
The valid range is from 10 to 160.
Use NAT IP
The NAT IP address used in SIP/SDP messages. This field is blank at the default
settings. It should ONLY be used if it's required by your ITSP.
STUN Server
The IP address or Domain name of the STUN server. STUN resolution results are
displayed in the STATUS page of the Web GUI. Only non-symmetric NAT routers
work with STUN.
Public Mode
Configures to turn on/off the public mode for Hot Desking feature. The default
setting is “No”.
Settings
Call Features
Off-hook Auto Dial
Configures a User ID/extension to dial automatically when the phone is off hook.
The phone will use the first account to dial out. The default setting is "No".
Off-hook Timeout
If configured, when the phone is off-hook, it will go on-hook after the timeout (in
seconds). The default value is 30 seconds. The valid range is from 10 to 60.
Bypass Dial Plan
Through Call
History and
Directories
Enable/Disable the dial plan check while dialing through the call history and any
phonebook directories. The default setting is “No”.
Disable Call Waiting

Disable Call Waiting
Tone
Disables the call waiting tone when call waiting is on. The default setting is "No".
Disable Busy Tone
on Remote
Disconnect
Disable the busy tone heard in the handset when call is disconnected remotely.
The default setting is “No”.
Disable Direct IP
Call
Disables Direct IP Call. The default setting is "No".
Use Quick IP Call
mode
When set to "Yes", users can dial an IP address under the same LAN/VPN
segment by entering the last octet in the IP address. To dial quick IP call, off hook
the phone and dial #XXX (X is 0-9 and XXX <=255), phone will make direct IP call
to aaa.bbb.ccc.XXX where aaa.bbb.ccc comes from the local IP address
REGARDLESS of subnet mask. #XX or #X are also valid so leading 0 is not
required (but OK). No SIP server is required to make quick IP call.
The default setting is "No".
Disable Conference
Disables the Conference function. The default setting is "No".
Disable in-call DTMF
Display
When it's set to "Yes", the DTMF digits entered during the call will not be displayed
on phone LCD. The default setting is "No".
