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.
