Cisco SPA 500 Series and Wireless IP Phone Field Reference Ext Tab B A codec resource is considered allocated if it has been included in the SDP codec list of an active call, even though it eventually might not be chosen for the connection. 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 phone), no other low-bit-rate codec can be allocated for subsequent calls. The only choices are G711a and G711u. Since two G.723.1/G.726 resources are available per IP phone, you should disable the use of G.729a to guarantee support for two simultaneous G.723/G.726 codecs. Dial Plan The default dial plan script for each line is as follows: (*xx|[3469]11|0|00|[29]xxxxxx|1xxx[2-9]xxxxxx|xxxxxxxxxxxx.). Parameter Dial Plan Enable IP Dialing Description Dial plan script for this line. The default is (xx.) (*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[29]xxxxxxS0|xxxxxxxxxxxx.) The dial plan syntax is expanded in the Cisco SPA to allow the designation of three parameters to be used with a specific gateway: • uid - the authentication user-id • pwd - the authentication password • nat - if this parameter is present, use NAT mapping Each parameter is separated by a semi-colon (;). Enable or disable IP dialing. Defaults to no. Cisco SPA 500 Series and WIP310 IP Phone Administration Guide 278
