Re: [Freeswitch-dev] error events for failed calls using'conferenceconf_name bgdial sofia/ip/user'

10 Mar 2010

      Thanks Anthony - 

I got it to work with the following:

FS Version : 16852 and later 16963M

"api originate sofia/10.50.48.232/+{my_tn_here}@10.50.50.50:5060
&conference(conf_uuid-TEST_CON) inline"

If I used api originate <dialstring> conference conf_uuid-TEST_CONF
inline then FS tried to make a conference of conf_uuid-TEST_CON@inline
.. using &conference(conf_uuid-TEST_CON) inline fixed that

2010-03-10 17:03:36.463558 [NOTICE] switch_ivr.c:1447 Transfer
sofia/internal/+{my_tn}@{my_gw} to conf_uuid-TEST_CON[conference@inline]

2010-03-10 17:03:36.465638 [DEBUG] switch_core_state_machine.c:133 No
Dialplan, changing state to CONSUME_MEDIA

---------

For others that may look at this later, my test code to get
"start-talking" and "stop-talking" events during Early Media using esl
lua (freesiwtch_src/libs/esl/lua) is

#!/usr/local/bin/lua

require("ESL")

local con = ESL.ESLconnection("localhost", "8021", "ClueCon");

con:sendRecv("event plain ALL")

ob_session_string = string.format("originate
sofia/internal/{MY_TN_NUMBER_HERE}@{MY_GATEWAY_HERE}
&conference(conf_uuid-TEST_CON) inline")

ff = con:api( ob_session_string )

print("** sent api")

if ff then

    print(ff:getBody())

    print(ff: getHeader("result"))

else

    print("no body")

end

cnt = 0

while cnt <= 40 do

    print("loop = " .. cnt )

    cnt = cnt + 1

    ev = con:recvEventTimed(1000)

    print( ev and ev:serialize("plain") or "no event this time" )

end

Some of your findings are incorrect.

The default behavior of originate is to return as soon as there is early
media. (sip 183)
Adding ignore_early_media=true is the opposite effect so you do not want
that.

bgapi just does the command in a separate thread so you don't want that
either.

api originate <dialstring> conference conf_uuid-TEST_CONF inline
will put the call in the conference the very instant it sees a 183 

If you see anything other than this, make sure you are on latest trunk
and do a console trace demonstrating otherwise.

use these commands for more details.

Anthony - 

The problem with api originate <dialstring> conference
conf_uuid-TEST_CONF inline is that it does not return until after the
call is answered - so I do not have events during early media.  I did
try to add {ignore_early_media=true} but it still did not return until
after I answered the phone (using esl lua for this test)

I also tried "bgapi originate
{ignore_early_media=true,origination_uuid=my_uuid_my_uuid_my_test_uuid}s
ofia/internal/+18015551212@10.50.40.50:5060
&conference(conf_uuid-TEST_CONF) inline", (I used a different TN, but
changed it for privacy) which makes the call and returns events before I
answer the call, BUT the conf bridge does not get involved (called)
until AFTER the origination call is answered.

Neither of these allows me to get "start-talking" and "stop-talking"
events during Early Media from the conf bridge because the conference is
not involved during the early media part of the call.

Brian - 

I should have been more detailed in my sofia string in the subject.  I
am aware that sofia/ip/user is not valid. Two examples sofia string I
use are below.

* If I used sofia/10.50.48.222/1002 AND that user is registered and
answers, then all works well.  If that user is not registered, I need to
get USER_NOT_REGISTERED

* If I use sofia/internal/+18015@10.50.40.50 (which is not a valid E.164
TN) then I should get DESTINATION_OUT_OF_ORDER or some other error
message.

consider 

api originate <dialstring> conference conf_uuid-TEST_CONF inline

this returns success+uuid or fail

Please read that there is no such thing as sofia/ip/user  (unless the ip
is an alias on the profile)

	My goals are:

	1)       To get "start-talking" and "stop-talking" events during
Early Media (before the call is answered) as well as after the call is
answered.  

	2)       If there are problems with the call, get events that
tell me why the call failed.

	The way I am doing it accomplishes the start/stop talking (in
early media) BUT if the call fails, I do not get events back letting me
know it failed and why.  I DO get CHANNEL_DESTROY and CHANNEL_STATE
events that IF I had the UUID, I could match against, but at this point
in the call I do NOT have that UUID AND when setting the UUID via
"origination_uuid=my_uuid_my_uuid_my_test_uuid", my UUID has not yet
been set, so as far as I can tell there is no way to match those events
with details my application has at the time.  

	The console shows the errors (Below are two examples of calls
that failed in I entered "bad" sofia locations), but they do not come
back as events.

	2010-03-05 14:52:20.109497 [ERR] switch_ivr_originate.c:2389
Cannot create outgoing channel of type [sofia] cause:
[USER_NOT_REGISTERED]

	2010-03-05 16:34:13.669509 [ERR] switch_ivr_originate.c:2389
Cannot create outgoing channel of type [sofia] cause:
[DESTINATION_OUT_OF_ORDER]

	So ... I am wondering is there a better/different way to do it,
is there a work-around, should I get events to tell me the dial had
problems, etc.

	I am using esl/lua and esl/java to experiment with this.  Both
get the same results (as I would expect).

	I have had this as a ~take-a-number on IRC for about a week, so
I thought I would add more detail and open it up to this group.  I
realize many of the same people do both, but hoped more eyes may look at
it here and give thoughts.

	===== From Pastebin ==== 

	I am not getting 'error' events in ESL [that match a UUID I can
track] when there is a problem with conference <conf_name> dial
sofia/myip/1006, so I can not tell what went wrong.  Is there a
work-around?  

	 I start a call in a conference from ESL (conference
conf_uuid-TEST_CONF bgdial
[origination_uuid=my_uuid_my_uuid_my_test_uuid]sofia/10.50.48.232/1006)

	 If the 'dial' works (meaning does not get an error) then I get
the events I want and expect.  If it errors (not able to make the call (
[USER_NOT_REGISTERED] | [DESTINATION_OUT_OF_ORDER] | etc. ) then I do
not get any events that tell me something went wrong.

	 Is there a work-around for this?

	=====================

	LUA Code  run from ./freeswitch.trunk/libs/esl/lua

	#!/usr/local/bin/lua

	require("ESL")

	myip = "10.50.48.239"  -- change this to your IP address

	myExt = 1006  -- change to one that is registered, then rerun
with an unregistered

	con = ESL.ESLconnection("localhost", "8021", "ClueCon");

	str = string.format("conference conf_uuid-TEST_CONF bgdial
[origination_uuid=my_uuid_my_uuid_my_test_uuid]sofia/%s/%s", myip,
myExt)

	con:sendRecv("event plain ALL")

	ff = con:api( str )

	print("** sent " .. str )

	print( (ff and ff:getBody() or "no body" ))

	cnt = 0

	while cnt <= 30 do

	    print("loop = " .. cnt )

	    cnt = cnt + 1

	    ev = con:recvEventTimed(1000)

	    print( ev and ev:serialize("plain") or "no event this time"
)

	end

	The printout is :
