<div>In continuation to my earlier post below i am giving some more details</div><div>about the problem.</div><div>I Created three subchannels one for normal call (SUB_REAL -0),second for callwaiting (SUB_CALLWAIT - 1), and third one for 3-way conference (SUB_THREEWAY - 2).</div>
<div><br></div><div>So i used SUB_REAL For normal call and set device FD using ast_channel_set_FD() function.</div><div>after this my deviceXYZ_read() and deviceXYZ_write() api are getting polled by asterisk</div><div>but when i set the same FD for call waiting scenario by keeping SUB_REAL Channel on hold,</div>
<div>deviceXYZ_write() and deviceXYZ_read() for subchannel SUB_CALLWAIT is not polled by asterisk.</div><div><br></div><div>I would like to know procedure how to use Same FD to make callwaiting or 3-wAY conference</div><div>
work?</div><div>I also saw the swap_subs() in some of the channel driver implementation.Does this do any mixing?? what is the purpose of this function?</div><div><br></div><div>Any help on this appreciated .thanks in advance</div>
