[Freeswitch-dev] error events for failed calls using 'conference conf_name bgdial sofia/ip/user'

Wed Mar 10 09:23:42 PST 2010

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 :
