How to Delete Issabel Call Recording Files

Issabel PBX, a popular open-source Unified Communication solution, saves call recordings in the directory /var/spool/asterisk/monitor/. Over time, these call recordings can consume significant disk space, leading to storage issues. To ensure your server continues to operate efficiently, it is necessary to manage and delete old or unnecessary call recordings periodically.

This article explains how to locate and delete Issabel call recording files safely.

1. Understanding the Default Location

By default, Issabel PBX stores all call recordings in the following directory:

/var/spool/asterisk/monitor/

Within this folder, call recordings are often saved with filenames containing the call date, time, and extension number. For example:

exten-101-107-20241211-122032-1733899832.3410.wav
