Local RTP Port 
This parameter defines the local RTP port used to listen and transmit. It 
is the base RTP port for channel 0. When configured, channel 0 will use 
this port _value for RTP; channel 1 will use port_value+2 for RTP. Local 
RTP  port  ranges  from  1024  to  65400  and  must  be  even.  The  default 
value is 5004. 
Use Random Port 
When set to "Yes", this parameter will force random generation of both 
the  local  SIP and  RTP ports.  This is usually  necessary  when  multiple 
phones are behind the same full cone NAT. The default setting is "Yes" 
(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. 
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  public  mode  for  hot  desking  feature  on  the 
phone. If set to "Yes", users would need fill in the SIP Server address for 
account 1 as well. Then reboot the phone. When the phone boots up, 
users will need enter SIP User ID and Password on the LCD to login and 
use the phone.
