Resource reservation of audio coders

The following information, which is applicable to the ATCA Multimedia Platform, should be added to the programming guide, possibly as a new chapter.

Resource Reservation of Audio Coders

The following sections describe the use of the IPML API and Device Management API in various scenarios for resource reservation of audio coders.

Outbound Call

1.Application reserves coders (RESOURCE_IPM_G711_20MS, RESOURCE_IPM_G723, RESOURCE_IPM_G726, RESOURCE_IPM_G729) and offers the reserved coders to the remote side.

2.The remote side picks G723, G726.

3.Application releases (RESOURCE_IPM_G711_20MS, RESOURCE_IPM_G729). This leaves (RESOURCE_IPM_G723, RESOURCE_IPM_G726) as the reserved audio coders.

4.The application proceeds with the call.

5.After the call is done, the application releases the coders (RESOURCE_IPM_G723, RESOURCE_IPM_G726). (Alternatively, the application can release all the reserved coders by specifying the enum RESOURCE_IPM_ALL_AUDIO_CODERS.)
