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 G.729a 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.
