ONE、[**]rtificial customer service mode
Firstly, consider that your artificial customer service only needs to connect with the tel set through the machine or also need to do service through mobile phone. If only need to do artificial customer service at office on working time and no need to work through mobile phone, V1 or B1 is more recommended rather than V3 or V5, which are dual SIM Card machine.

TWO、[**]ccording to operation degree of difficulty
If want to pursue of easy operation, V1 is recommended since V series marketing machine is adopted MP3 format, which don’t need to transfer to BIN format and can directly copy to TF memory card and inserted into the equipment. V1 is much more easy to operate than B1. What’s more, the equipment is more durable with the external TF memory card to store MP3 voice format. If the memory card is abnormal what you need to do is changing a new one.

THREE、[**]ccording to only need to replace manual dialing and without playing advertising voice
If consider that the marketing machine play voice doesn’t show obvious effects, you only need the equipment to filter invalid number and the customer service staff conduct service of the valid number. B1 or B0 is more recommended form the aspect of the production cost and no need to purchase V series which cost are higher.
