DSP Resource Usage
Making a call through an IP-CS with a PS requires a certain number of DSP resources, depending on the
codec used. If all DSP resources are in use, this operation cannot be performed. To ensure a minimum
level of performance, DSP resources can be reserved for VoIP communication. (→ 5.5.3 DSP Resource
Usage)

When a caller has dialled the extension number of a PS but the CS is busy, the caller hears a busy tone.

The number of digits allowed for a PS extension number is determined by the PS model. See your PS
documentation for details.
