[Freeswitch-users] Problems reading DTMFs sent by A

[Helena Garcia-Nieto]

Ups, sorry, I changed the name of the var to send the config on the mailing list, but in the server config the names are equal!!!

 

Any idea why I am not able to get the DTMFs?

<action application="play_and_get_digits" data="2 5 1 7000 #
$${base_dir}/conf/outgoingcall.wav $${base_dir}/conf/outgoingcall.wav myvar
\d+"/>

<action application="log" data="INFO helena2 -1-${mybar}-"/>

 

Looks like you have a typo here - myvar vs mybar

Hi All!

I am trying to read some DTMFs dialed by A after freeswitch picks the call.
My aim is to recollect the DTMFs and create a bridge between the incoming
call and the extension he dialed but I am not able to get the dialed DTMFs.

I've tried read and play and get digits action with no success. It seems
none of the applications I used on the dialplan is able to read the sent
dtmfs. I am using it on the public dialplan since the phone is getting to
that dialplan form port 5080. I tried also transferring the call to the
default dialplan and using the actions there with no success either.

                <extension name="Read Example">
                                <condition field="destination_number"
expression="^(334)$">
                                        <action application="answer"/>
                                        <action
application="play_and_get_digits" data="2 5 1 7000 #
$${base_dir}/conf/outgoingcall.wav $${base_dir}/conf/outgoingcall.wav myvar
\d+"/>
                                        <action application="log" data="INFO
helena2 -1-${mybar}-"/>
                                </condition>
                </extension>

I've traced on the server and I can see the RTP event packet with the digits
getting the server but in my console log I can see there were no info got:

I've tried with the read action as well:

        <extension name="try2" continue="true">
                        <condition field="destination_number"
expression="^(333)$">
                        <action application="answer"/>
                        <action application="sleep" data="1"/>
                                <action application="read" data="0 10
$${base_dir}/conf/outgoingcall.wav res 10000 #"/>
                                <action application="phrase"
data="spell,${res}"/>
                                <action application="log" data="INFO HELENA
--${res}__"/>
                        </condition>
                </extension>

I cannot hear the played wav from my softphone, although I can see in the
server trace that it is sent, so maybe I have some NAT problem for the RTP
but since I can see the RTP EVENT getting the freeswitch server I don't
think it is affecting.
I've tried configuring the softphone to send RFC2833 RTP events and also to
send the dTMF in band. Both cases the result on the log was an empty
variable.

I am pretty new at freeswitch so I guess I am forgetting to do something or
doing something wrong. May be there is a better option/action to do this!
I'll appreciate any help you could give me!

Thanks in advanced

Helena
