ATA Voice Field Reference PSTN Line page (SPA3102) B Use DNS SRV Whether to use DNS SRV lookup for Proxy and Outbound Proxy. DNS SRV Auto Prefix 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. Proxy Fallback Intvl 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 Proxy Redundancy The PAP2T makes an internal list of proxies returned in Method DNS SRV records. In normal mode this list will contain proxies ranked by weight and priority. If the parameter Based on SRV port is configured, the PAP2T creates a list in normal mode first, and then inspects the port numbers based on the 1st proxy's port on the list. The default is Normal.
