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 GXV-3140s are
behind the same full cone NAT. The Default setting is YES. (This parameter must
be set to NO before Direct IP Calling will work)
Keep-alive Intervals (s)
This parameter specifies how often the GXV-3140 sends a blank UDP packet to
the SIP server in order to keep the “pin hole” on the NAT router to open. The
Default setting is 20 seconds.

are displayed in the STATUS page of the Web UI. Only non-symmetric NAT
routers work with STUN.

other calls, the default system ring tone will be used.
If the server supports the Alert-Info header and standard ring tone set (like
Bellcore) is specified, then the Caller ID field must be left “blank” and the ring
tone will be used based on the info header from the server
Call Progress Tones

parameters from the local telecom provider. By default, they are set to the North
