General bank management recording system must be an audio digital recording system that can record, monitor, inquire, back up, count and manage multiple telephones at the same time (single telephone at most 160). I know that Pioneer Audio has XF-PCI/ PRO(YH) series, which is an open professional recording system integrating voice recording, recording file storage, recording data backup, recording retrieval and playback, system management and other functions. With the help of a large-capacity computer hard disk as the storage medium, it completely breaks through the traditional concept of telephone recording. XF-PCI/ PRO(YH) series bank management integrates global mainstream PBX (such as Nortel, Avaya, Alcatel, Cisco, Ericsson, Siemens, NEC, Mitel, Motorola, etc.) and CTI middleware (such as Avaya AES, PDS, Aspect, Genesys, ICM, Motorola and Nortel M65438). It has played a great role in inquiring and discovering the cause of the accident in time and providing accurate and reliable original recording records. Now it has been widely used in banking departments, such as "hotline service telephone recording", "complaint telephone recording", "key post telephone recording" and "paging desk recording".
