Well, I just tested today's snapshot: FreeBSD 7.2, pfSense 1.2.3RC1 (2008-05-18), and I still get no traffic in qVOIPUp. Again, going back to 1.2.2 release works fine with the same configuration.
Also reported by another user here (although with ipsec): http://forum.pfsense.org/index.php/topic,15450.0.html
Let me know what info would help ….....
regards, ...... Charlie
