PSTN Line page (AG310 and SPA3102) Field Proxy Fallback Intvl Proxy Redundancy Method Description 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 The PAP2T makes an internal list of proxies returned in 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. Voice tab > PSTN Line page > Subscriber Information section Field Display Name User ID Password Use Auth ID Auth ID Call Capacity Description Display name for caller ID. Extension number for this line. Password for this line. To use the authentication ID and password for SIP authentication, select yes. Otherwise, select no to use the user ID and password. The default is no. Authentication ID for SIP authentication. Maximum number of calls allowed on this line interface. Choices: {unlimited,1,2,3,...25 }. Default is 16. Note that the ATA device does not distinguish between incoming and outgoing calls when talking about call capacity. Note: unlimited = 16 Voice tab > PSTN Line page > Audio Configuration section A codec resource is considered as allocated if it has been included in the SDP codec list of an active call, even though it eventually may not be the one chosen for the connection. So, if the G.729a codec is enabled and included in the codec list, that resource is tied up until the end of the call whether or not the call actually uses G.729a. If the G729a resource is already allocated and since only one G.729a resource is allowed per device, no other low-bit-rate codec may be allocated for subsequent calls; the only choices are G711a and G711u. On the other hand, two G.723.1/G.726 resources are available per device. Therefore it is important to disable the use of G.729a in order to guarantee the support of two simultaneous G.723/G.726 codec. Linksys ATA Administration Guide 146
