Hi all, I have an issue to send DTMF to an external extension (goes through my PSTN) My actual config is: |--|FXS-phone FS------LAN-----CISCO SPA3000--| |--| FXO-to-pstn Either I make a call from FXS of a soft SIP phone in my LAN the DTMF I send are not recognized at all by the number I call. When I send the DTMF I see in the console: freeswitch@internal> 2014-06-17 15:19:59.846809 [DEBUG] switch_rtp.c:5788 RTP RECV DTMF 1:1600 2014-06-17 15:19:59.846809 [DEBUG] switch_channel.c:486 RECV

have no isea where to look. Is it a config to change within FS or SPA3000 ? What type of conf should I check ? In the past I had a Digium card+ asterisk and I had never had an issue with dtmf since the default config did work. I am new to FS so any idea is welcome. Thanks
