Proxy and Registration

Parameter
Proxy
Outbound Proxy
Use Outbound Proxy
Use OB Proxy In Dialog
Description
SIP proxy server and port number set by the Service
Provider for all outbound requests. For example:
192. 1 68.2. 1 00:6060.
SIP Outbound Proxy Server where all outbound
requests are sent as the first hop.
Enables an outbound proxy (for example,
172.20.2. 1 :5060—port is optional) or a domain name
such as sip.server.com as long as this name is a fully-
qualified domain name. If set to no, the Outbound Proxy
and Use OB Proxy in Dialog fields are ignored.
Defaults to no.
Optionally, the proxy can be configured (SPA5xx only)
for Survivable Remote Site Telephony (SRST) support.
The proxy is configured with an extension that includes
a statically-configured DNS SRV record or DNS A
record. Configuring the proxy allows for failover and
fallback functionality with a secondary proxy server.
For example:
For SRV Record:
sip.server.com:SRV=node1.sip.server.com:5060:p=1:w=
50| n ode2.sip.server.com:5060:p=2:w=50
NOTE Set "Use DNS SRV" to no and "DNS SRV Auto
Prefix" to no.
For A Record:
sip.server.com:A=172.20.2. 1 ,172.20.2.2
NOTE Set "Use DNS SRV" to no and "DNS SRV Auto
Prefix" to no.
Whether to force SIP requests to be sent to the
outbound proxy within a dialog. Ignored if <Use
Outbound Proxy> is no or <Outbound Proxy> is empty.
Defaults to yes.
