Audio Configuration

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.

Description
Enables the SPA9000 to perform an attended transfer operation by ending the current call
leg and performing a blind transfer of the other call leg. If this feature is disabled, the
SPA9000 performs an attended transfer operation by referring the other call leg to the
current call leg while maintaining both call legs. To use this feature, select yes. Otherwise,
select no.
The default is no.
User ID or URL of the auto-answering streaming audio server. When only a user ID is
specified, the current or outbound proxy is contacted. Music-on-hold is disabled if the
MOH Server is not specified.
Makes the SPA9000 perform a transfer when a conference call has ended. Select yes or
no from the drop-down menu.
The default is Yes.
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).
Maximum number of conference call participants. The range is 3 to 10.
The default is 3.
To use IP dialing, select yes. Otherwise, select no.
The default is no.
Comma-separated list of emergency number patterns. If the outbound call matches one of
the patterns, the SPA9000 disables hook flash event handling. Hook flash event handling
is restored to normal when the phone is on-hook again. If you leave this field blank, the
SPA9000 has no emergency number.
Enter the ID number of the mailbox for this line.
