Thunderbird 2.0.0.4 (X11/20070604) |
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.
Thank you very much for your assistance,
- Michael Hines
