How to decrypt the filename of the Call Recording

[timerider]

I don't know the reasoning of the OP but my record_name is changed to record_name=${sip_from_user}-${destination_number}-${uuid}.${record_ext}

As mentioned above, some call scenarios can end up with misleading recording name but since I also include the uuid there are no potential conflicts.
The one particular customer that requested the above name format was coming from a different call recording option and is used to similarly named files in the CRM system. They record all calls, but generally only download certain calls to import into their other system. Most of the "saved" calls are from internal users making outbound calls.

I toyed with the idea of leaving in the uuid, but the circumstances where names might clash (small scale Pbx here) haven't occurred in near 15 years so left it out, I might revisit that, or if scale got larger add it in though
