Finally, I changed fifo for valet_parking and It is working. It is also working with BLF. Here is the code for those who want the same information:

<extension name="parkinglot">
      <condition field="destination_number" expression="^(18[0-2])$">
        <action application="valet_park" data="lot $1"/>
      </condition>
    </extension>
    <extension name="parkingkey">
      <condition field="destination_number" expression="^(park\+)(18[0-2])$">
        <action application="transfer" data="$2 XML context_1"/>
      </condition>
    </extension>
The parkingkey extension is important for, in my case, Granstream phones working with BLF. I put park+180 in multi-function key.

Everything is working fine.

Hi all,

I am configuring a blue.box server with freeswitch. I am tweaking blue.box to add fifo call park. I followed instructions from this wiki page http://wiki.freeswitch.org/wiki/Park_%26_Retrieve .I can park the call but cannot retrieve it. When I dial the same extension where I parked the call (Usually, it is supposed to pick up the parked call), the call is parked in another park slot. Here is my configuration:

    <extension name="parking_slots">
        <condition field="destination_number" expression="^(18[0-2])$" break="on-false">
        <action inline="true" application="set" data="slot_count=${fifo(count $1@${domain_name})}"/>
        <action inline="true" application="set" data="slot_count=${slot_count:-3:2}"/>
    </condition>
    <condition field="${slot_count}" expression="^\:0$" break="always">
        <action application="unset" data="fifo_chime_list"/>
        <action application="set" data="fifo_chime_freq=0"/>
        <action application="fifo" data="${destination_number}@${domain_name} in undef local_stream://moh"/>
        <anti-action application="fifo" data="${destination_number}@${domain_name} out nowait"/>
    </condition>
    </extension>

I have found this in the log file:

EXECUTE sofia/sipinterface_1/ext@X.X.X.X set(slot_count=180@X.X.X.X:0:1:0:0:0)

The number 1 is the parking slot number. It changes to the next available parking slot (In this case, number 2) everytime I dial 180.

Am i missing something?

Thanks for your help!

Fred
