[asterisk-users] T38 faxing - UDPTL creation failed

[=?utf-8?B?IpronZ794e3h6e0i?=]

Good question.
I can't simulate it right now so I will try it today or so...But I'm not
expecting, that it help, because I tried couple of ways before and restart
was the only way.

But thanks anyway. Any other ideas?
