Command
CHG NKT <time-out setting>
PRT NKT
CHG ES1/CHG ES2
If the IP addresses entered for ES1 and ES2 are the same and both are
not 0.0.0.0 or for external servers, an error message is generated and the
input is not accepted. Any value between 1000 and 60000 can be entered
for the port. If the port value is outside of that range, an error message is
generated. Just the port (and not the IP addresses) can also be configured.
This is accomplished by entering data similar to the following:
=>chg es1 0 5400
The value 0 for the IP address is interpreted as: 0.0.0.0. This means the
Echo Server runs locally using the configured port value.
The port values both default to 10 000. If an IP address is configured, it is
also necessary to configure the port. An error message is generated if no
port is configured but an IP address is configured.
If both Echo Servers are not configured, then the LTPS on the Signaling
Server or the Voice Gateway Media Card uses two local instances of the
Echo Server. If both Echo Servers are configured, then the LTPS uses the
external Echo Servers. If an external Echo Server fails, that functionality is
lost unless the external Echo Server implements a transparent redundancy
scheme. The external Echo Server is responsible for its redundancy and
reliability.

or port numbers have been configured, then these appear in place of the
