[Freeswitch-users] How to populate Voice recording metadata with custom CRM data?

Hi All, I am using Freeswitch 1.0.4 (Latest Windows Installer version) on Windows 7 Ultimate for testing Assuming an outbound call, what would be the most sensible approach to pass custom CRM data into the voice-recording? I would like the voice recording of the call to include the customers social security number in the file title, or even metadata. In other words, is there a way to pass custom info, at time of call, to the dialplan for use in the creating the voice recording. Any pointers would be much appreciated Rgds Roly
