External IP address to substitute for the actual IP address of the SPA9000 in all outgoing
SIP messages. If 0.0.0.0 is specified, no IP address substitution is performed.
If this parameter is specified, the SPA9000 assumes this IP address when generating SIP
messages and SDP (if NAT Mapping is enabled for that line). However, the results of
STUN and VIA received parameter processing, if available, supersede this statically
configured value.
The default is 0.0.0.0.
External port mapping number of the RTP Port Min. number. If this value is not zero, the
RTP port number in all outgoing SIP messages is substituted for the corresponding port
value in the external RTP port range.
The default is 0.
Interval between NAT-mapping keep alive messages.
The default is 15.
