frequency (in minutes) the Unicorn 3112 refreshes its
registration with the specified registrar. The default
interval is 60 minutes (or 1 hour). The maximum
interval is 65535 minutes (about 45 days).

This parameter defines the local SIP port the Unicorn

The default value for FXS port is 5060.
The default value for FXO port is 5062.
Local RTP port
This parameter defines the local RTP-RTCP port pair
the Unicorn 3112 will listen and transmit. 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

FXS port is 5004.
The default value for FXO port is 5008.
Use random port
This parameter, when set to Yes, will force random
generation of both the local SIP and RTP ports. This is
usually necessary when multiple Unicorn 3112 are
behind the same NAT.
