Bridge call channels

[case...@gmail.com]

Hi All,

On my custom whistle-esk app, I'm trying to bridge two or more existing call legs (channels) together from calls that my app has "won". For example, if call A had a Call-ID of "abc" and call B had a Call-ID of "bcd", then I'd like to have a function that could be as simple as bridgeChannels("abc", "bcd",...). To do this, I need to figure out how to send a call command through AMQP to ecallmgr to bridge the channels.

FreeSWITCH has this function:

(https://wiki.freeswitch.org/wiki/Mod_commands#uuid_bridge)

uuid_bridge

Bridge two call legs together.

Usage: uuid_bridge <uuid> <other_uuid>

uuid_bridge needs atleast any one leg to be answered.

I've found a definition for "Bridge Endpoints" in ecallmgr here: https://github.com/2600hz/kazoo/blob/master/core/whistle-1.0.0/src/api/wapi_dialplan.hrl but I'm not sure how to use this (e.g. what application name do I use to call it, where do I specify the Call-ID, etc.) At the moment I can make a softphone ring and bridge that to a channel by Call-ID using the "Bridge" command specified in the above URL, but I don't want to bridge to a new channel - just bridge two or more existing channels.

Is there any way to do this with ecallmgr through AMQP?

Thanks!

Casey

Look at the pickup dialplan command in wapi_dialplan. Only works for
two legs though; you'll need to create and transfer into a conference
for more legs.

Exactly what I needed - it worked beautifully. Thanks for the quick reply!  One more question - any thoughts on how to cancel a bridge (or media / echo / conference, etc.)? I've tried sending a park command, but it doesn't seem to do anything.

Here's my park command JSON:

{

  "Event-Name": "command",

  "Event-Category": "call",

  "Call-ID": "OTNhMjRlNTUwZTYxMmEzNjYwNmQ2N2I2NWJiMjk5Y2U",

  "App-Name": "CallMeMaybe",

  "App-Version": "0.0.1",

  "Msg-ID": "84d7877c-096a-4041-9c61-7c181086e827",

  "Insert-At": "now",

  "Server-ID": "CallMeMaybe_ReceiveQueue",

  "Application-Name": "park"

}

Thanks again,
Casey
