★ Cooperation with the telephone recording box: through RJ11 port to match up with wired telephone recording box and achieve the outgoing recording, incoming screen popup and so on through phone card. 
★ Cooperation with analog voice board: through RJ11 telephone wire to connect the analog voice board, through the phone card  to provide "anti-polar signal" telephone line for the voice card, and alternative operators telephone line (PSTN). 

★With the call center software to achieve through the phone card access call center system and various applications.
★ Cooperation with PBX: through RJ11 telephone line to connect PBX, which through the phone box to call out. When phone is on, FWT will provide the "reverse pole signal" to inform PBX that phone is on. [**]t the same time, it will provide a caller ID. [**]gainst for mostly telephone lines can not provide "reverse pole signal", resulting in part of PBX function can not be used. What's more, some of the mobile phone cards cost low tariffs, it  provides more cheap choice of communication charge for enterprise exchange customers.
★ Cooperation with the traffic telephone: telephone line can be connected to the call center dedicated telephone, through traffic telephone to outgoing call. The caller ID will be displayed when the phone is connected. 
★ Cooperation with the wireless fixed-line card application: part of the fixed wireless card need to use a dedicated decryption card stickers. Part of the area can be customized built-in key to achieve the use of decryption stickers.
★ Cooperation with ordinary landline telephone: through the telephone wire to connect ordinary landline telephone, the equivalent of a "wireless fixed platform"; can easily achieve incoming, outgoing call, caller ID and so on.
