[Freeswitch-users] Prolems with DTMF

[Rudolf Denert]

Hello,

I'm not sure which one is it. But I think I send the digits in RFC 2833. All devicves are supporting RFC 2833.

The equipment:
(VoATM)
Allied Data Copperjet 1614 (ISDN)
Siemens Euroset 5020 phone

(MGCP)
Thomson SpeedTouch 780WL
Siemens Euroset 5020 phone

(SIP)
AVM Fritz!Box 7170
Siemens Euroset 5020 phone

If necessary I can send my configuration.

Hello, 

I have problems with sending DTMF. The freeswitch server recieves the digits from my telefon (SIP account) if I activate DTMF with: 
<action application="start_dtmf"/> 
in my dialplan. 

The line 
<--param name="dtmf-type" value="rfc2833"/--> 
in sofia.conf.xml is active, too. 

But than I have the problem that the other phone doesn't work. It is a VoATM device. The curious thing is that I see the digits in the logfile whiche were sent from the phone. In the first example I saw nothing. 

Does anybody have an idea??? 


Are you trying to send digits inband or RFC2833? Unless there's a compelling reason not to, we recommend 2833. What is the equipment on the far end looking for?
