Thanks to your answer, 

I forgot to say that the softphones were in another subnet.

I have solved the problem by editing the following file

vi /usr/local/freeswitch/conf/sip_profiles/internal.xml

and change ext-rtp-ip to ext-sip-ip for the local ip of the server.

     <param name = "ext-rtp-ip" value = "$$ {local_ip_v4}" />
     <param name = "ext-sip-ip" value = "$$ {local_ip_v4}" />

This solved my audio and dtmf issues

try check what audio codecs and what kind of DTMF you are using in clients (in softphones), and change it to something else...

Hello 

I have installed freeswitch version 1.10.0 from the source codes. But when connecting the softphones I experienced the following problems. 

Zoiper (ext 1000) = When calling the ivr I do not hear anything and when pressing the options do not dial DTMF signals to the control panel. 

Phonerlite (ext 1001) = I hear perfectly the IVR, but when pressing the options not connected the DTMF signals to the control panel. 

Anyone had this configuration problem?

thanks.
