Im working with Asterisk PBXand freeswitch PBX.<br>
I have a challenge with FXO card in Asterisk and i could not solve it yet.<br>
I hope you could guide me in this regards.<br>
When i want route the call to FXO channels, Before the callee answer<br>
the phone (pick up phone), The channel is answered with FXO card. How<br>
can change this treat so that the callee dont answer the phone, the<br>
channel dont answered with FXO card. I have this challenge with FXO<br>
gateway too.<br>
This challenge is more important when using callfile to generate call<br>
using DAHDI/g0/<br>
When using it,All attempts to generate call are answered in CDR<br>
field(disposision=answered).<br></blockquote><div><br></div><div>This is how analog works because it cannot detect when the far end<br>answers with any kind of reliability. The FXO port considers the call<br>answered as soon as it finishes dialing the last digit. There is some<br>
attempt to do this using line supervision by polarity reversal. However,<br>this is not normally supported by the telco.<br><br><br></div><div>Richard</div></div></div></div>
