USB Recording
Yealink phones support manual recording during a call or automatic recording once the call is set up. Yealink
CP920 phones support recording when the phone is idle, helping users record an important discussion in the local
conference room. Before recording, ensure that the USB flash drive has been connected to the IP phone or USB
port of the PSTN box CPN10 (CPN10 is only applicable to CP920 phones). USB recording is only applicable to
T57W/T54W/T53W/T53/T48U/T48S/T48G/T46U/T46S/T46G/T43U/T42U/T42S/T41S/T29G/T27G/CP920 phones.
The recorded calls are saved in *.wav format and include a date/time stamp, the other party’s number/IP address/-
name (or the first person’s number/IP address/name you called), duration of the call and the recording file size. For
example, 20160422-1515-Bob was created on Apr. 22, 2016, at 15:15 and you have a call with Bob. If the record-
ing is created when the phone is idle, the file is saved with a keyword "idleREC". Recorded calls can be played on
either the phone itself or on a computer using an application capable of playing *.wav files.
Note: Yealink phones support USB flash drive in FAT32 or NTFS (NTFS is not applicable to T43U/T42U) format.
Important: Before recording any call, especially those involving PSTN, it is necessary to know about the rules and restric-
tions of any governing call-recording in the place where you are. It is also very important to have the consent of the person
you are calling before recording the conversation.
