we have problem here with outbound calls. Many devices for example Zyxel, WELL 8820IP, Interbell and some software clients Ekiga v3.3.2 and SJ Phone drops call after 32 seconds. I think it could be some new standard from 2007, because Ekiga v4.0 seems ok and mentioned hardware devices don't have new firmware since this year. Can you confirm that please? I'm attaching some captures.

Thank you
