Using Post Call Action, it is possible to construct a URL to retrieve the audio file at the end of the phone call.

The following parameters are required in your Post Call Action in order to make this work.
- Date/Time
- Caller ID
- Transferred Number

When you receive the PCA it will most likely look something like this:
transfer_num=8475551234&datetime=2009-04-07%2017%3A23%3A04&callerid=8476766624

The format for the findme recorded file is:
http://www.ifbyphone.com/user_recordings/[PRE-ACCOUNTID]/[ACCOUNTID]/findme/[FINDMEID]/[timestamp]_[callerid]_[transfer_num].wav
An example URL would be:
http://www.ifbyphone.com/user_recordings/3/3881/findme/0/20090407172304_8476766624_8475551234.wav

Your Account PRE-ID is the going to be the first set of digits from your account.

For example if your account ID is 1234  then your Pre-ID is 1.  If your account ID is 12345  then your Pre-ID is 12.  If your account ID is 123456 then your Pre-ID is 123. 

If you are using an API Find me (you created it on the fly) your FINDMEID will always be 0.
