Something like the following perhaps??? Is this possible?
This would be a bridge without answer would it not?

Hello everyone:
I think what Anthony wants is (please excuse me if I'm wrong - but what I'm assuming is) a call to come in - let's say that its DID goes to person A. He wants to ring person A, let person A pick up, and then bridge the call.
When working at an Asterisk VoIP vendor, I had a call in which a gentleman wanted just that. I think they paid for incoming calls or something.
Anthony, please let us know if that's accurate.
Thanks,
Kareem

You can't.
Why would you need that? Are you trying to forward inbound calls from the
pstn to an ivr without answering them?
That could get you in trouble FYI.

Hi all,
When I dial a number from Originator Gateway, It will route to Freeswitch
Server and then FS will bridge the call to Terminator Gateway as below.
Terminator Answer the call (and runs playback, and look for DTMF).
|Originator Gateway|---------------> |FreeSwitch |------------------>
|Terminator Gateway|
I used bridge application to route call to Terminator.
But my requirement is that when Terminator answer the call (Respnd with
200OK) , Freeswitch should NOT Answer call for A leg (Originater Gateway).
How can be this done?
Thanks in advance.

can you create a pastebin with the two scripts in question? We'll take
a look and see if we can figure out what's going on.

To get what you want.
I also had a problem that you get two rings, then an answer then to the
system generated ring tone, which was confusing some of our (not to bright)
callers.
As we don't use callerID I turned that flag off in the openzap.conf.xml file
- I thought that this would do what I wanted (answer the instant the call is
detected), but the change in the config file does not make it all the way
down to the point where it takes action. At this point I hacked the code to
get what I wanted. I have to create a JIRA entry with the details yet.
As far as I understand, this is the right place for OpenZap, as it is a
product of the FS project.

At this point there is not a separate mailing list for OpenZAP stuff
so here is as good a place as any to ask OZ questions.

Scott, I imagined that it could be an OpenZap problem, but I didn't find an
OpenZap mailing list, so I sent the email to FS list. Do you know where can
I find more information about OpenZap hardware support and developement
status (I have special interest in Loop Start)??
Anthony and Ognjen, I've tried tone detection and thanks to that FS is
detecting hung up, but I faced the problem that tone detector answer the
call...
That's my dialplan:
<extension name="extension_name">
<condition field="destination_number" expression="^919999999$">
<action application="tone_detect" data="busy 425,0 r +100 hangup 16
4"/>
<action application="bridge"
data="sofia/internal/1003%${server-domain-name},
sofia/internal/1004%${server-domain-name}"/>
</condition>
</extension>
When I receive a call from PSTN, tone detection answer the call (the caller
hears only one first tone and then hears "nothing" until I pick up the call
on softphone).
So, I think that tone detection solution does not resolve my problem... Is
there any other possibility to detect hang up without answering the call
(using Loop Start signaling) or have we to wait until OpenZap is completely
developed?
Thanks in advance.

Ok, as discussed with Tony on IRC channel I followed his directions which
lead to a successfull outcome (like it always does I might add .
One has to use tone_detect app in FreeSWITCH dialplan in order to check
for busy tones coming from the PSTN side and if matched fire a hangup
application. This is the snippet of my test dp that does the trick (from
extension Local_extensions in default.xml):
<anti-action application="tone_detect" data="busy 425,0 r +100 hangup 16
4"/>
<anti-action application="bridge"
data="user/${dialed_extension}@${domain_name}"/>
This means that FS will listen to freq of 425 Hz and wait for 4 positive
detection to fire up hangup app with code 16 which is NORMAL_CLEARING (425
Hz is the freq telco here uses; for other countries I suggest getting the
ITU world tones pdf file and check there):

I tried similar setup with my analog card (X100P) and I'm having same
issue. Call is not hungup on the oz side once the caller ends. My telco
doesn't use polarity reversal for singalling hang up so I'm guess I'm stuck
to detecting busy tone from the telco side. I'll try to modify tones.conf
accordingly.

This is a common issue with analog phones even traditional answering

I'm sure you must have had an answering machine at some point that has
dial tone as the message it receives.
Unless FreeSWITCH has some hint that the call has hungup it will not
stop trying to complete the call.
If the other side is sending a busy tone to indicate hangup it's
possible to use the tone_detect app to pick
up on the tones and abort the call.
Another thing you could do if you have unlimited inbound is explicitly
answer the call in the dialplan before
you call your sip phones this will give you a more profound hangup
detection but it will make every call count
even when nobody answers.

Hi all,
I'm configuring my home PBX using FreeSwitch. I'm using a X101P card
configured as FXO (conected to analog PSTN line) and I have several IP
phones and softphones conected to FreeSwitch.
I can call from an IP phone to other IP phone (the same with the
softphones) and also from an IP phone (or softphone) to an external number
thought PSTN.
When I call from an external analog phone to FreeSwitch, I bridge the
call to all internal IP phones and softphones and they ring, but the problem
is that when I hang up the call in the external phone, all internal phones
(IP phones and softphones) keeps ringing...
I'm pretty sure the problem is that FreeSwitch don't receive the hang
up, because I cann't see anything on the log.
I've also created my own tones.conf for my country (Spain) but I'm not
sure if it's ok (but I have the same problem with hang up)
I've googled the list, and I've found several people with a similar
problem but no solution...
That's my pastebin with the most importants printouts and config files:
http://pastebin.freeswitch.org/6822
Thank you very much in advance.

I have an application that requires answering machine detection. I have not
been able to locate any documentation indicating that there is explicit
support for answering machine detection. I have received recommendations on
call flows that would include DTMF entry by the called party to detect by
implication answering machines, however, I need an explicit methodology. My
question is, does anyone have any experience with ATAs that might have this
capability. I am interested in any solution that might even include Avaya,
Cisco, or other hardware device interfaced with Freeswitch that would
provide an explicit answering machine detection capability.
