Re: [Freeswitch-users] FreeSWITCH ends the calls after receiving DTMF from the Callee.

13 Feb 2012


      You could put a breakpoint in the spots where i added debugging lines
in the patch and get a stack trace from that point.

Anthony,
Thanks for your reply.
Iam not setting the input callback from the mod_managed code. I tried to
find out the caller function of setDTMFCallback(void *cbfunc, char
*funcargs) by debugging FS. It goes to disassembly code. So don't know who
is setting it out. Iam stuck, I don't know how to proceed. Any help would be
appreciated.
Also before bridging I tried setting bleg.DtmfReceivedFunction = null; It
didn't help.
Thanks in advance
Srini

This illustrates that something in your code or something close to it is
setting the input callback.  Maybe a lib you are using on top of managed?

Anthony,
I do see the two prints as...
[CRIT] switch_cpp.cpp:697 ASSIGN INPUT CALLBACK 003F2559
[CRIT] switch_cpp.cpp:1274 BRIDGE input callback func: 003F2559
Complete debug log is attached and I have highlighted them.

Try this patch to print more debug info.
It seems somewhere in the managed code something is assigning an input
callback and its being executed and returns false which makes the call
end.

The Lua script works fine. No problem in capturing the DTMF from both the
call legs.
Only in Mod_Managed I  have issue. Its simple 3 lines of code nothing
fancy...
public void Run(AppContext context) {

 context.Session.Answer();
 var newSession = new ManagedSession("sofia/gateway/foo/callenumber");
 freeswitch.bridge(newSession, context.Session);
}
FreeSWITCH version is

I tried this lua script which should be the same thing:
b_leg = freeswitch.Session("sofia/internal/foo@bar.com", session);
...
...
freeswitch.bridge(session, b_leg);
See if you get the same problem running this lua code, I was passing dtmf
fine.
Internally, the code should not even use a callback capable of ending
...
...
the call as you described unless your program has an input callback of
dtmf handler function.
Also make sure you are on a recent build of FS.

Anthony,
Thanks for your response.

I have not defined any of these input_callback or dtmf_callback.
I have attached the log with debug level.
