Call recording data. Size per min

Anyone know what size a call recording is per minute? How many k or mb?

Also is there a way to enable compression on recordings like mp3?


Depends on the format really. I have some ulaw 8k 8bit mono recordings which are about 900KB per minute.

Yikes. Do you know if it’s possible to change the format that freepbx records to?

Let’s say it was 1mb per min, we would need around 10 to 20gb per day, 600gb per month.


Yes you can change the recording format. Using GSM or G729 would be much smaller. G729 requires an additional chargeable codec.
