Specific sets of SIP parameters are inter-dependent with each other. To prevent conflicting
parameter values from being applied, per-line values always take precedence over the
corresponding set of global values.
For example, if a parameter value is configured for one of the per-line sets, all parameters from
that set are applied and all parameters from the corresponding global section are ignored, even
if some of the parameters within the global set are not defined in the per-line set.
SIP PASSWORD MASKING
The "mask sip password" configuration parameter can be used to mask a user's SIP account
password in the server.cfg and local.cfg files (downloaded from the IP phone's Web UI
troubleshooting page for debug purposes). The parameter is disabled by default.
Configuring SIP Password Masking
Use the following procedure to configure SIP password masking using the configuration files.
CONFIGURATION FILES
For specific parameters you can set in the configuration files, see Appendix A, the section,
Basic, Global Settings"
SIP PRECEDENCE EXAMPLE
The following example shows the SIP proxy feature and example schema for storage and
parsing of the SIP configuration parameters.
The following SIP configuration is assumed:
# SIP network block
sip proxy ip:
sip proxy port: 5060
sip registrar ip:
sip registrar port: 4020
sip line3 proxy ip: siparator.vonage.com
sip line3 proxy port: 0
Line3 specifies per-line values for proxy IP address and proxy port, so the phone uses those
parameter values for SIP calls made on that line. However, because those parameters are part
of the SIP network block, the phone does not apply any of the global SIP network block
parameters. So even though the global parameters configure a SIP registrar, Line3 on the
phone ignores all global network block parameters. Since line3 does not contain a per-line SIP
registrar entry, the phone does not use a registrar for that line.
Note: Global SIP parameters apply to all lines unless overridden by a per-line
configuration. Per-line settings are configurable for lines 1 through 7.
