[Freeswitch-users] update to blf on parked calls goes out.

Wed Oct 16 05:59:35 MSD 2013

Here is the scenario.  Park a call using park+1.  Park light illuminates.  As soon as a set sends another subscriber to park+1, Freeswitch responds with a notify with state terminated.

That would seem to me to be a bug or I have a setting re park incorrect?

  Subject: [Freeswitch-users] blf on parked calls goes out.

  I pursued this awhile back with no results, it is still a puzzling issue.  Any help what so ever would be appreciated.

  When I park a call I get a notify message telling me the call park is confirmed.  Then at a random time, 2 seconds to 20 seconds out of the clear blue I get a message showing the call park is terminated.   The call is still active and can be picked up using the button on the phone.  The problem does not exist with extension blf.   using the console (fs_cli) at debug level 7 shows no activity at the time of the disconnect.

  using version   FreeSWITCH Version 1.5.5b+git~20130721T031327Z~adf5e2f6ec (git adf5e2f 2013-07-21 03:13:27Z)

  It seem to remember it worked correctly in the past but I am no longer sure.
