| How does voice codec selection for H.323 work with SmartWare? | |||
| Article Id #: 58 | |||
The selection of a specific codec is somewhat tricky with the H.323 protocol. In SmartWare a specific codec can be entered at 2 different locations: a. in the h323 gateway configuration b. in the h323 interface configurationThe following example exemplifies a typical configuration: ...
The codec configuration in the gateway specifies the 2 codecs G.723 6.3kbps and G.729 as the set of allowed codecs. This set of codecs is sent to the remote H.323 gateway (or gatekeeper) during the capability exchange phase. The codec specified in the interface 'myif' is the preferred codec to be used. SmartWare places this codec is on top of the list of allowed codecs which is sent during the capability exchange phase. Note that the preferred codec specification only works when FastConnect procedure is used. Otherwise it is without effect. |
