Description
Enable the use of <Outbound Proxy>. If set to no, <Outbound Proxy> and <Use OB Proxy
in Dialog) is ignored.
The default is no.
SIP Outbound Proxy Server where all outbound requests are sent as the first hop.
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.
The default is yes.
Enable periodic registration with the <Proxy>. This parameter is ignored if <Proxy> is not
specified.
The default is yes.
Allow making outbound calls without successful (dynamic) registration by the unit. If No,
dial tone will not play unless registration is successful.
The default is no.
Allow answering inbound calls without successful (dynamic) registration by the unit. If
proxy responded to REGISTER with a smaller Expires value, the PAP2T will renew
registration based on this smaller value instead of the configured value. If registration
failed with an Expires too brief error response, the PAP2T will retry with the value given
in the Min-Expires header in the error response.
The default is 3600.
Expires value in sec in a REGISTER request. PAP2T will periodically renew registration
shortly before the current registration expired. This parameter is ignored if <Register> is
no. Range: 0 – (231 – 1) sec
Whether to use DNS SRV lookup for Proxy and Outbound Proxy.
The default is no.
If enabled, the PAP2T will automatically prepend the Proxy or Outbound Proxy name with
_sip._udp when performing a DNS SRV lookup on that name.
The default is no.
This parameter sets the delay (sec) after which the PAP2T will retry from the highest
priority proxy (or outbound proxy) servers after it has failed over to a lower priority
server. This parameter is useful only if the primary and backup proxy server list is
provided to the PAP2T via DNS SRV record lookup on the server name. (Using multiple
DNS A record per server name does not allow the notion of priority and so all hosts will
be considered at the same priority and the PAP2T will not attempt to fall back after a fail
over).
The default is 3600
PAP2T will make an internal list of proxies returned in DNS SRV records. In normal
mode, this list will contain proxies ranked by weight and priority.
if Based on SRV port is configured the PAP2T does normal first, and also inspect the port
st
number based on 1 proxy's port on the list.
The default is Normal.
