Hi, Is it possible asterisk could provide voip client have auto authentication ability? so in the voip client we don't have to input user and password and what we have to input in voip client just ip gateway? Just in the voip client, because in asterisk we have to input user and password in the extension file. have anyone tried like that before? or at least there's any way to do like that? very thank you in advance. rafa -------------- next part -------------- An HTML attachment was scrubbed...
