To accommodate a recording solution for a variety of office telephone implementations, Checktel offers several models, for a maximum of

8 concurrent calls and
60 concurrent calls, i.e. twice 30 concurrent calls.

Models are available for both network connections on the ISDN telephone network as well as telephone calls made through the internet by means of VoIP/SIP.

For (Euro) ISDN the (subscriber) line type dictates the model to be used.

For ISDN-2 (BRI) a model for 1 to 4 ISDN-2 (BRI) lines is available, and for ISDN-30 (PRI) a model for one or two ISDN-30 lines.

For VoIP, the (expected) number of concurrent calls dictates the model to be used.

All models can be integrated into one system, with a maximum capacity of 100 concurrent calls, to form a system that can handle both traditional telephone calls as well as VoIP calls.
