B

Conference Bridge URL	This feature supports external conference bridging for n-way
	conference calls (n > 2), instead of mixing audio locally. To use
	this feature, set this parameter to that of the server's name;
	for example, conf@myserver.com:12345 or conf
	(which uses the Proxy value as the domain).
	Default: blank
Conference Bridge Ports	Maximum number of conference call participants. The range
	is 3 to 10.
	Default: 3
Enable IP Dialing	To use IP dialing, select yes. Otherwise, select no.
	Default: no
Emergency Number	Comma-separated list of emergency number patterns. If an
	outbound call matches one of the patterns, the SPA9000
	disables call waiting, hook flash event handling, and fax tone
	detection. Operation is restored to normal when the phone is
	on-hook again. If you leave this field blank, the SPA9000 has
	no emergency number.
Mailbox ID	Enter the ID number of the mailbox for this line.

Audio Configuration section

NOTE 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 codecs.

Preferred Codec

Preferred codec for all calls. (The actual codec used in a call still depends on the outcome of the codec negotiation protocol.) Select one of the following: G711u, G711a, G726- 16, G726-24, G726-32, G726-40, G729a, or G723

Default: G711u
