<P align=left>A codec resource is considered as allocated if it has been

<P align=left>active call, even though it eventually may not be the one chosen
for the connection. So, if the G.729a</P>
<P align=left>codec is enabled and included in the codec list, that resource is
tied up until the end of the call</P>
<P align=left>whether or not the call actually uses G.729a. If the G729a
resource is already allocated and since</P>
<P align=left>only one G.729a resource is allowed per SPA, no other low-bit-rate
codec may be allocated for</P>
<P align=left>subsequent calls; the only choices are G711a and G711u. On the
other hand, two G.723.1/G.726 <FONT face=ArialMT size=2></P>
<P align=left>resources are available per SPA. Therefore it is important to
disable the use of G.729a in order to</P>
<P align=left>guarantee the support of 2 simultaneous G.723/G.726
codec.</P></FONT></FONT></DIV>
