How to install the Asternic CDR module in FreePBX 13 via the command line
If you experience issues when trying to upload the latest FreePBX Asternic CDR module into FreePBX version 13, here is a recipe to install the module via the command line that seems to work:
First log into the server via ssh, then run these commands:
fwconsole ma delete asternic_cdr
fwconsole ma downloadinstall http://download.asternic.net/asternic_cdr-1.6.3.tgz
That would reinstall the latest Asternic CDR FreePBX module and make it available.
Thanks to James Cocke for the information!
