Local RTP port  

This parameter defines the local RTP-RTCP port pair the IPPH 202 will listen and transmit signals.  
It is the base RTP port for channel 0.  When configured, channel 0 will use this port _value for RTP 
and the por1 for its RTCP; channel 1 will use por2 for RTP and por3 for 
its RTCP. 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 IPPH 202 are behind the same NAT.

  

NAT Traversal  

This parameter defines whether the IPPH 202 NAT traversal mechanism will be activated or not. If 
activated (by choosing “Yes”) and a 

STUN server address

 is also specified, then the IPPH 202 

will automatically follow the STUN client specifications.  Under this mode, the embedded STUN 
client inside the IPPH 202 will attempt to detect if there is a (and type of) firewall/NAT it is sitting 
behind through communication with the specified STUN server.  If the detected NAT is a Full 
Cone, Restricted Cone, or a Port- Restricted Cone, the IPPH 202 will attempt to use its mapped 
public IP address and port in all of its SIP and SDP messages.  If the NAT Traversal field is set to 
“Yes” with no specified STUN server, the IPPH 202 will periodically (every 20 seconds) send a 
blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.  

Keep Connected 
Interval  

This parameter specifies how often the IPPH 202 sends a blank UDP packet to the SIP server in 
order to keep the “hole” on the NAT open.  

Use NAT IP:  

NAT IP address used in SIP/SDP message.  Default is blank.  

Proxy-Require  

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.  

Send DTMF  

This parameter controls how DTMF events are transmitted. There are 3 ways: In-Audio which 
means DTMF is combined in audio signal (not very reliable with low-bit-rate codec), via RTP 
(RFC2833), or via SIP INFO.  

DTMF Payload 
Type  

This parameter sets the payload type for DTMF using RFC2833  

Send 
Anonymous  

If this parameter is set to “Yes”, the “From” header in outgoing INVITE message will be set to 
anonymous, essentially blocking the Caller ID from displaying.  

Send Flash 
Event  

This parameter allows users to control whether to send a SIP NOTIFY message indicating that the 
phone’s Flash key has been pushed, or just to switch to the voice channel when users press the 
Flash key.
