When I tried to set the variable dtmf_type=info, or in sip profile parameter dtmf-type=info, would FS send the SIP INFO packet. For instance, if I called an IVR and pressed 2 after the call got answered by the IVR, I was expecting to see the message similar to below, but I did not see it. Is there any other variables that needs to be set? INFO sip:2143302100@172.17.2.33 <sip%3A2143302100@172.17.2.33> SIP/2.0 Via: SIP/2.0/UDP 172.80.2.100:5060 From: <sip:9724401003@172.80.2.100 <sip%3A9724401003@172.80.2.100>>;tag=43 To: <sip:2143302100@172.17.2.33 <sip%3A2143302100@172.17.2.33>
