Voice Transcoding Overview
This section provides a high-level overview of how the voice transcoding functionality is configured. After
you insert the SPA-DSP in the SIP, the SPA-DSP is activated, and you can identify the status of the SPA-DSP,
by executing the show platform command. If the SPA-DSP is operational and working fine, the show platform
command output will display OK in the Status for SPA-DSP. Before you configure the voice transcoding
functionality, you must enable the SPA-DSP. After you enable the voice card and set the SPA-DSP in DSP
farm mode using the dsp services dspfarm command, you can create the DSP-farm service profiles.
DSP Farm Profiles
DSP-farm profiles are created to allocate DSP-farm resources. DSP-farm profiles can only be created after
you set the DSP SPA in DSP farm mode. Under the profile, you select the service type (transcode), associate
an application (SBC), and specify service-specific parameters such as codecs and maximum number of sessions.
A DSP-farm profile allows you to group DSP resources based on the service type. Applications associated
with the profile, such as SBC, can use the resources allocated under the profile. You can configure multiple
profiles for the same service. The profile ID and service type uniquely identify a profile, allowing the profile
to uniquely map to a SBC application. After creating the profile, you need to attach the profile to an application
and enable the DSP farm profile.
