[asterisk-users] Problems with supervised transfer and agents

Hi list.
    We are having some strange behavior with supervised transfers made by
agents. If a call who came from a queue to an agent wants to be supervised
transfer to another exten, if the other exten dont't answer the phone, i
lost the call.

Here is a simple log of the behavior with the explanation.  8702 call to the
queue (8820). The call is answered by the Agent 8911 (in Sip/8704), then,
the agent try to do a supervised transfer to Sip/8703.  At this point the
agent didnt get any ringback or anything, only silence (and in the log
constantly show this "
Jul 31 13:30:51 WARNING[2547] chan_sip.c: Asked to transmit frame type 64,
while native formats is 8 (read/write = 8/8)"). After the timeout of the
transfer (15 secs), the agent receive a busy signal, instead of recover the
call, and the person who called (8702), in matter of seconds, receive a busy
too.

The log here.

Anybody knows whats happening or what i am missing?. One thing to notice, if
i use instead of agents, with CallbackLogin(), i use Addqueuemember() with
sips directly, this problem  it never ocurs..

P.D.: it happened with asterisk 1.2.5, i upgraded to 1.2.10, but the problem
persists.

thanks.
Ivan.

Hi everybody

 

 

Does anyone here have a sample code written  in Visual Basic 6 that could
share with me ??

I have to design a Monitor Interface and I don?t know how to start it.

 

Thanks in advance.
