[Freeswitch-users] Unbridge Call

[Luiz Fernando Softov]

Hi everyone.


I have this problem making outbound call. Maybe someone can help me with
this.

I'm have a service in C (TCP Server),  where i receive all calls.


+--------+                             +--------+
| A 1001 |--> make call -> dialplan -> | socket |
+--------+                             +--------+

<extension name="outcalls">
    <condition>
        <action application="socket" data="127.0.0.1:8084 async full"/>
        <action application="hangup"/>
    </condition>
</extension>

After i accept the connection on port 8084 i send a connect command,
and receive the CHANNEL_DATA event.


In this service I do all the work of billing and control of active calls.

I have a internal structure, of my extensions (numbers in my FS)

IF EXTENSION HAVE MONEY i will send this commands to connection

to make a bridge between A [1001] and B [1003]

****

sendmsg\n
call-command: execute\n
execute-app-name: set\n
execute-app-arg: dialed_extension=1003\n\n

sendmsg\n
call-command: execute\n
execute-app-name: set\n
execute-app-arg: continue_on_fail=true\n\n

sendmsg\n
call-command: execute\n
execute-app-name: bridge\n
execute-app-arg: user/${dialed_extension}@${domain_name}\n\n

****

- Call work fine, WITHOUT <uuid>, WITH <uuid> i receive this WARNING
- [WARNING] mod_sofia.c:1281 Asynchronous PTIME not supported, changing our
end from 30 to 20

The phone ring, and i answer the call, normal!


But now I stopped because I not know, how to CANCEL the bridge (UNBRIDGE)
and do something with the A-leg.


"Something, like, HANGUP B-leg, and play a sound file to A-leg, then hangup
the call."

I tried, but all commands i have sended like

sendmsg\n
call-command: execute\n
execute-app-name: hangup\n
execute-app-arg: CHANNEL_UNACCEPTABLE\n\n

or

sendmsg\n
call-command: execute\n
execute-app-name: break\n\n

Do nothing with the call

I tried with and without "event-lock: true"

I receive only this in FS log

[DEBUG] switch_core_session.c:1151 Send signal sofia/internal/
1001 at 192.168.211.69[BREAK]

I tried with and without "event-lock: true"

I need to do this such as: credit is over, I need to cancel the current
bridge and play a sound to the user and hangup call

or to simple hangup a call

I receive this in FS console LOG after a-leg or bleg hangup a phone and
call terminated

[DEBUG] switch_ivr.c:614 sofia/internal/1001 at 192.168.211.69Command Execute
hangup()
[DEBUG] switch_core_session.c:2614 sofia/internal/1001 at 192.168.211.69Channel
is hungup and application 'hangup' does not have the zombie_exec flag.
[DEBUG] switch_ivr.c:657 sofia/internal/1001 at 192.168.211.69 skip receive
message [AUDIO_SYNC] (channel is hungup already)

This is for each "sendmsg" i send after bridge was answered.


Sorry about my english...
