The DSP costs of the extensions/CO lines involved in the operation are not included in the per-unit DSP resource count.

Two-way recording also requires a conference CO line. For an example of the required DSP resources, see 5.1.18 DSP Resource

Usage.
Example 1: Small Office
In a small office (e.g., 32 employees), the necessary number of CO lines and extensions is likely to be
relatively small. In addition, the expected load on the system will also be small.
(For clarity, unused services are not included in the table.)

DSP Cost = Number of Ports × Resource cost per port (unit) × Load
*1
In the example above, the total DSP cost is 18.55. In such an environment, a PBX with a DSP S card (max.
63 DSP resources) would be sufficient.
Example 2: Call Center
In a call center, both the number of CO lines and number of extensions are likely to be very high. Also, since
employees are constantly receiving calls, the system load will be high. Furthermore, calls are often recorded
at call centers to provide quality-of-service monitoring.
