Please describe which scenario applies to you: (1) Your Asterisk box shares an analogue line with an ordinary telephone. You want the person sitting at that telephone to be able to answer it and prevent the Asterisk box friom answering it. This is where you need a Wait() in your dialplan. (2) Outgoing calls from your Asterisk box are showing up as answered even whether or not the person at the far end picked up their telephone. -- AJS Note: Originating address only accepts e-mail from list!

[asterisk-users] Channel is answered by FXO card before callee answered the phone(pick up phone)
Hello Experts. Im working with Asterisk PBXand freeswitch PBX. I have a challenge with FXO card in Asterisk and i could not solve it yet. I hope you could guide me in this regards. When i want route the call to FXO channels, Before the callee answer the phone (pick up phone), The channel is answered with FXO card. How can change this treat so that the callee dont answer the phone, the channel dont answered with FXO card. I have this challenge with FXO gateway too. This challenge is more important when using callfile to generate call using DAHDI/g0/ When using it,All attempts to generate call are answered in CDR field(disposision=answered). Im waiting for your replying and Thanks. With Regards.Mojtaba -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

With Regards.Mojtaba I believe that is a well known behavior of Zaptel/DAHDI, given that many analog lines that would be attached to an FXO card supply little or no indication of an answered call, calls are considered answered once dialing is complete. You will need to use an alternate technology if you want to know if or when the caller has answered.

This is how analog works because it cannot detect when the far end answers with any kind of reliability. The FXO port considers the call answered as soon as it finishes dialing the last digit. There is some attempt to do this using line supervision by polarity reversal. However, this is not normally supported by the telco.

When i want route the call to FXO channels, Before the callee answer

can change this treat so that the callee dont answer the phone, the
channel dont answered with FXO card. I have this challenge with FXO
gateway too.
This challenge is more important when using callfile to generate call
using DAHDI/g0/
When using it,All attempts to generate call are answered in CDR
field(disposision=answered).
Im waiting for your replying and Thanks.
With Regards.Mojtaba
If you mean that Dial(DAHDI/g0/${EXTEN}) gets answered straight away, I think
that behaviour is normal. There isn't much in the way of supervisory
information coming along an analogue line, for want of a D-channel.
If you mean that the FXO card shares a line with a normal phone and you want
to be able to answer an -incoming- call on that phone, then you need a Wait()
in your dialplan before any Answer(). That will give time for someone to
answer the phone before Asterisk does; the ringing will stop, and the
extension will stop being processed.

Thanks with Regards.Mojtaba Mojtaba, It's not an exact science, but I believe what you want is the callprogress setting in chan_dahdi. Keep in mind that it can detect false positives, etc. Look in chan_dahdi.conf.sample for more information [1]. Give it a try. It may work for you..but it may not...
