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: 10.30.11.154

sip proxy port: 5060

sip registrar ip: 10.44.122.37

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
