Hi,

Sorry to add to my original post, but, I have opened ports 5060-5070 and 10000-20000.

Is there a particular port that relates to DTMF or is is likely to be some kind of NAT issue?

Hi All,
I have a FreeSWITCH server running behind a firewall and can successfully connect a Jitsi software client to the server remotely. I can dial 5000 from Jitsi and hear audio, but when I dial a DTMF digit,nothing happens.

I have tried configuring Jitsi to use different DTMF methods, but none seem to work.

It is a vanilla install of FreeSWITCH, Running on Debian 7 installed via the packages so the config files will be default.

Any ideas?

Thanks

Richard
