Notes:
1. 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 PHONE ADAPTER, 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 PHONE ADAPTER. Therefore it is important to disable
the use of G.729a in order to guarantee the support of 2 simultaneous G.723/G.726 codec.

Dynamic Payload Types and SDP Codec Names
Note: You should only need to change the payload type mappings if you are interworking with a non-
standard implementation.

2. The configured dynamic payloads are used for outbound calls only where the PHONE ADAPTER
presents the SDP offer. For inbound calls with a SDP offer, PHONE ADAPTER will follow the caller’s
