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 :
