+to Set Up an Outbound Proxy</title><shortdesc>This topic explains how to specify an outbound proxy server in
+the SIP Managed Profile. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>To specify an outbound proxy server, call <xref href="GUID-CDE67614-1A7A-3082-8D8D-71645668A0DE.dita#GUID-CDE67614-1A7A-3082-8D8D-71645668A0DE/GUID-901C0EE4-646C-351A-9E13-8972F2CBAC8F"><apiname>CSIPManagedProfile::SetParameter()</apiname></xref> with
+the <xref href="GUID-51E1043D-5FC6-3A79-911B-816CE8043A25.dita"><apiname>KSIPOutboundProxy</apiname></xref> parameter and an IP address. </p>
+<p>You can also let the stack automatically discover the proxy address by
+setting <xref href="GUID-A46F476F-40D1-3893-952F-8E958132653F.dita"><apiname>KSIPResolveProxy</apiname></xref> to <codeph>ETrue</codeph>. </p>
+<ul>
+<li id="GUID-09F02A7F-11D3-513B-8182-CB052CB0C5AB"><p>By default or if <xref href="GUID-A46F476F-40D1-3893-952F-8E958132653F.dita"><apiname>KSIPResolveProxy</apiname></xref> is
+set to <codeph>EFalse</codeph>, <xref href="GUID-51E1043D-5FC6-3A79-911B-816CE8043A25.dita"><apiname>KSIPOutboundProxy</apiname></xref> sets
+the IP address of the outbound proxy. If the proxy server cannot be found,
+the profile enabling fails. </p> </li>
+<li id="GUID-A9051F50-43D7-549C-87EC-175F12661642"><p>If <xref href="GUID-A46F476F-40D1-3893-952F-8E958132653F.dita"><apiname>KSIPResolveProxy</apiname></xref> is
+set to <codeph>ETrue</codeph>, <xref href="GUID-51E1043D-5FC6-3A79-911B-816CE8043A25.dita"><apiname>KSIPOutboundProxy</apiname></xref> sets the
+backup IP address for the outbound proxy. The SIP stack attempts to find the
+proxy through a DHCP request and only uses the backup address if the proxy
+discovery process fails. </p> </li>
+</ul>
+<p>Backwards compatibility note: <codeph>"sip:0.0.0.0"</codeph> is a valid
+value for <codeph>KSIPOutboundProxy</codeph>. It is equivalent to requesting
+DCHP discovery without specifying a backup address. </p>
