Recording Using a Record Key
You can record calls by tapping a record key on the phone. The SIP-T48G IP phone supports

Two ways of call recording:

to trigger a recording.
 URL Record: The phone sends an HTTP URL request to trigger a recording. Contact your
system administrator for the predefined URL.

 During an active call
 When calls are on hold or muted
 During a blind or attended transfer
 During a conference call
The Record and URL Record keys are not available when:
