[Freeswitch-users] How do you split bridged calls ?

Tue Jun 5 03:18:03 MSD 2012

Hello 

After several mistakes I find out that if you want to break a bridge, from a
socket application, and keep managing the two legs in your application the
solution is:

uuid_transfer <uuid> -both park inline //the inline does the magic here.

then you can play phrases,get dtmf... and even re-bridge the two legs.

Thanks to those who point me to the right direction.

I dropped your log file into our pastebin here:
http://pastebin.freeswitch.org/19209

The log shows that the issue is not that FS is only trying to process the
first leg, which can be seen by looking at lines 507 and 714. The problem
here is that your inline dialplan is not being parsed properly. What's
happening is that uuid_dual_transfer is literally trying to send the A leg
to destination number "m:^:phrase:queue_position,5^ inline" and the B leg to
destination number "m:^:phrase:queue_position,3^ inline". 

What are you trying to do with each leg of the call? I see that you are
trying to announce the queue position, but what do you want to have happen
after that? As it stands your call legs would probably just end after the
announcement because there's nothing more to do.

Hello,

I keep trying to split a bridged call.

Using playback wav I have audio on both leg, but in my IVR I will need
different message to be played to each leg.

I do not know if this is a bug or not:

I have audio only on one leg using uuid_transfer or uuid_dual_transfer for
phrase.

Test 1

         api uuid_transfer <uuid> -both 'm:^:phrase:queue_position,5^
inline'

Test 2:

         api uuid_dual_transfer <uuid> 'm:^:phrase:queue_position,5^ inline'
'm:^:phrase:queue_position,3^ inline'

notice queue_position 5 for the first and 3 for the second.

Please find attach a FS log showing for the second test that FS is only
looking to process the first leg.

Details regarding the application and log.

my dialplan

    <extension name="unpark">

      <condition field="destination_number" expression="^5100$">

         <action application="set" data="park_after_bridge=true"/>

         <action application="socket" data="192.168.1.100:8022 async full"/>

      </condition>

    </extension>

Why use phrase instead of files, mainly experience with IVR building, easier
to change, manage, can use parameters and language customization.

Application

Let's be optimistic and forget about any errors.

Leg 1 call fs ext 5100

         goes thru socket app

         api create_uuid for outgoing call

         execute playback phrase

         some other event initiate originate (in my case http request
result)

         bgapi originate
{origination_uuid=created_UUID}sofia/internal/1001%192.168.1.11 5100  //
this way leg 2 ends also on my socket app

Leg 2 outgoing call (ext 5100) 

         execute playback phrase

the 2 legs are there so now using DTMF handling on leg 1

         DTMF 1 bridge the two legs

         DTMF 2 broadcast msg on the 2 leg , this work but wasn't used in
the log provided

         DTMF 3 uuid_transfer or in our case uuid_dual_transfert

leg 1 = sofia/internal/1000 at 192.168.1.11

leg 2 = sofia/internal/1001 at 192.168.1.11

Sorry for the late reply, but I just wanted to mention for the sake of
posterity/SEO that you could also use 'uuid_dual_transfer' if you want to
send each leg to a different destination.

Or you  could use uuid_transfer, such as "uuid_transfer <uuid> -both park
inline". If you want to use dialplan apps in the transfer just use the
"inline" dialplan, and not XML.
