A
EXT IP 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.
Defaults to blank.
EXT RTP Port Min 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.
Defaults to blank.
NAT Keep Alive Intvl Interval between NAT-mapping keep alive
messages.
Defaults to 15.
