[Freeswitch-users] FreeSWITCH call recording missing header information

[Joel Serrano]

Another option is to just rely on CDRs, you can have FS post them remotely
AND save them to local disk...

1- record
2- end call
3- when local cdr is generated parse it (json/xml)
4- search for the var that has the recording location
5- do stuff....


Cheers,
Joel.
