[Asterisk-Users] SIP: Trouble with "Moved temporarily" (302)

Hm... I dunno... 

The way it works now I am not able to call an *unkown* Nikotel SIP user 
(i.e. I am not aware of which username is mapped to the 99xxxxxxxxxx 
number), and that's not really so nice. Of course the other option is to 
tell Nikotel to re-consider their user setup, but I don't think that'll 
work. ;->

I can see the redirection danger though: If Nikotel decided to send me 
through PSTN instead then I'd suddenly be charged for the call even 
though I still think this is a free VoIP call. So my option here would be 
to operate two Nikotel accounts, of which only one has a pre-paid budget, 
and the other one without budget is used for redirected/VoIP calls. This 
need results from the fact that only authenticated Nikotel users can call 
Nikotel users.

Which, by the way, makes me long again for some smarter extension 
matching rules than just [1-9], X and N: I'd love to have [alpha] or 
[alphanumeric] or [k-m], and possibly also [length:7-9] for variable 
numbering plans.

Cheers, Philipp
