Hi,

Just an update...  it work!! :) Thanks for the tip.


If it help others, my solution was:

Dialplan action:
<action application="lua" data="intercept.lua ${hash(select/last_uuid/".${val1}.")}"/>

Lua script:

intercept_uuid = argv[1] or nil
if (intercept_uuid == nil) then
    cm.error("Missing uuid to intercept")
    return
end

fifo_bridge_uuid = api:execute("uuid_getvar", intercept_uuid .. " fifo_bridge_uuid") or "_undef_"
fifo_status = api:execute("uuid_getvar", intercept_uuid .. " fifo_status") or "_undef_" -- TALKING when the call is answered

if (fifo_bridge_uuid ~= "_undef_" and fifo_status == "_undef_") then
    myuuid = session:get_uuid()
    -- fifo intercept / bridge uuids (caller / extension trying to intercep)
    api:execute("uuid_bridge", myuuid .. " " .. fifo_bridge_uuid)
else
    -- normal intercept
    session:execute("intercept", "-bleg " .. intercept_uuid)
end

I'm my setup i have analog phones (using atas) and IP phones, to be able to have call waiting in the analog phones i put a fifo for each account connected to the ata. So a call going to an ata extension is always from a "self" fifo.


The problem is that, in the office extensions can capture/intercept each other, when the person on that desk is out, by pressing **+extension, answering the call (even if is just to say that the person is out... ), this works for ip phones, but it fails when the ringing phone is the analog extension because of the fifo.


Mike:
     you give me one idea, i could could uuid_bridge the uuid (a-leg) from the caller in the fifo to the channel uuid trying to execute the intercept. I guess once i done this the calls gets hangup in the fifo and the b-leg (agent) channel should hangup as well.

    i'm think of something like: uuid_bridge <original caller uuid> <uuid extension that is requesting intercept >
    I will try to do test this tomorrow. i post here the results.
  


Thanks,
António

Why do you want to intercept the agent anyway, won't that hangup on the customer?

in mod_fifo, the agent is called by mod_fifo before it is bridged to the a leg, therefore if you are trying to grab that a-leg while that b-leg is ringing, you will need to do so using the a-leg uuid, there is no connection to the b-leg until after the b-leg answers.
