<div>Hello</div>
<div> </div>
<div>to bring more precision on this, actually, the CON message is well received, and call is established but no audio can be heard - until a DTMF is issued !</div>
<div> </div>
<div>I am currently using the ITU setting.</div>
<div> </div>
<div>Any ideas as to what is happening ?</div>
<div> </div>
<div>many thanks</div>
<div> </div>

<div>Hello</div>
<div> </div>
<div>I am connected to an Ericsson switch, via a TE121 & Ast 1.6. I am only doing outgoing calls (ie my box to the E/// switch, then to the world !)</div>
<div> </div>
<div>I use libss7 1.0.2 and dahdi 2.2.0, most of calls are setup correctly - An IAM message is sent, and a reply ACM is received when the call is answered by the B party.</div>
<div> </div>
<div>In some occasion, I receive a CON message back - in this situation, the call is established, but I get NO audio (the message also is dumped as unknown, it looks like it is not listed in isup.c / message2str - but it has no effect on the processing itself).</div>
<div> </div>
<div>1/ Anyone receiving these messages and processing them successfully ?</div>
<div> </div>
<div>2/ on the side, I am trying to use chan_ss7 but it does align - how can I debug the ISUP message exchange when loading the module ? </div>
<div> </div>
<div>thanks for your answers, </div>
