A recording system for recording calls between callers and agents of a transaction processing system includes an Internet Protocol (IP) gateway, an interface configured to operatively couple the IP gateway to the transaction processing system, a communication network operatively coupled to the IP gateway, where the IP gateway is configured to convert a call received from the transaction processing system into IP protocol data, and provide the IP protocol data to the communication network. Also included is a memory storage system operatively coupled to the processor and configured to store the IP protocol data, a processor operatively coupled to the communication network and configured to receive the IP protocol data, and a switch controlled by the agent and settable between a record-on mode and record-off mode such that the recording system records the call if the switch is set to the record-on mode and does not record the call if the switch is set to the record-off mode. The recording system can also playback various recorded messages, and play music while a call is on hold.
