How do I check for that? Here's my settings: 1. firewall off (I'm not behind NAT) 2. *not checked*: "use SIP INFO message instead of RTP rfc2883 for DTMF" 3. all sound devices working properly 4. I'm using SIP through an sip-proxy (asterick-based) 5. My audio codecs in this order: PCMU, PCMA, GSM, speex
I'm not familiar with the specific SIP details, but I would be more than happy to provide more information to solve this problem.
