Digital ISDN Recorder
A cost-effective decision when there are a large number of telephone extensions is to record calls before the PBX. Audiomemo is then connected in parallel to the incoming (E1/T1 PRI or BRI) lines and records all incoming and outgoing traffic. It is used when it is not necessary to know which extension took the call or to record the communication between extensions.
For this type of recorder SmartWORKS™ NGX cards are used.
