CallRecorder is an excellent tool, because it addresses many of the various issues that concern call recording. Firstly, the application needs to be running all the time; that way, as per settings, calls can be recorded as and when required. The best feature of this application is that the recording can be done automatically, and in case a call needn’t be recorded, that setting is also available.
The software can organize these settings whether the number is known, not known, a contact, a group setting, and many permutations and combinations besides. It is also feasible to set actions for these rules: like ask before record, all incoming, and more.
