Can a Cisco DSP be used as a conference bridge?

This figure shows a successfully registered Conference Bridge resource in Cisco CallManager. Unable to configure the available DSP to be used for hardware conferencing in Cisco CallManager on a Cisco IOS voice gateway with DSP resources already allocated.

Can a DSP be used for transcoding and termination?

If a DSP is assigned for a conferencing session, then it cannot be used for transcoding or voice call initiations, or terminations. However, transcoding and voice calls can share the resource of a single DSP. Conferencing needs a dedicated DSP, but not a dedicated packet-voice DSP module (PVDM)2. For example, PVDM2-64 contains four DSPs.
