<p>Hi,<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>I have an application where my Javascript hanguphook code calculates a value
(e.g. the cost of the call which can only be calculated post hangup) and I need
to have that value appear as a field in the cdrs.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>As the ‘session’ object is no longer available for javascript
logic post hangup, I can’t figure out how to ‘set’ a user
variable post hangup, such that it can be written to the cdr when the state
changes from CS_HANGUP -> CS_REPORTING. Maybe it’s just
not possible……? It would be a pity to have to resort to writing out
cdrs from the javascript itself and duplicating what fs does so well already.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Any advice / suggestions would be appreciated.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Best Regards<o:p></o:p></p>
