Configuring a SIP Proxy Server
You can configure SIP proxy servers in the Proxy and Registration section of the EXT tabs: 
1. Select Admin > Advanced.
2. Enter your service provider name in the Proxy field. 
Make Call Without Reg
Enables making outbound calls without successful (dynamic) 
registration by the phone. If set to no, the dial tone plays only 
when registration is successful.
Defaults to no.
Register Expires
Enables answering inbound calls without successful (dynamic) 
registration by the phone. If the proxy responds to a REGISTER 
with a lower expires value, the phone renews registration based 
on that lower value instead of the configured value.
If registration fails with an “Expires too brief” error response, the 
phone retries with the value specified in the Min-Expires header 
of the error.
Defaults to 60 seconds.
Ans Call Without Reg
If enabled, the user does not have to be registered with the 
proxy to answer calls.
Defaults to no. 
Use DNS SRV
Enables DNS SRV lookup for the proxy and outbound proxy.
Defaults to no.
DNS SRV Auto Prefix
Enables the phone to automatically prepend the proxy or 
outbound proxy name with _sip._udp when performing a DNS 
SRV lookup on that name.
Defaults to no.
Proxy Fallback Intvl
Sets the delay after which the phone retries from the highest 
priority proxy (or outbound proxy) after it has failed over to a 
lower priority server. 
The phone should have the primary and backup proxy server list 
via DNS SRV record lookup on the server name. It needs to know 
proxy priority; otherwise, it does not retry.
Defaults to 3600 seconds.
Proxy Redundancy Method
Select Normal or Based on SRV port. The phone creates an 
internal list of proxies returned in the DNS SRV records. 
If you select Normal, the list contains proxies ranked by weight 
and priority.
If you select Based on SRV, the phone uses normal, then inspects 
the port number based on the first-listed proxy port.
Defaults to Normal.
