Is it available a list of hidden rules voxalot use to make calls? For example: if I make a rule to call 800 numbers in Italy (I say voxalot to use an italian provider) it doesn't work as a hidden rules (A call to:800297297 will get forwarded to sip:800297297@public.sip.magrathea.net) takes the control.
The working rule seems to be:
Pattern: _80.
Replacement: 80${EXTEN:2}
Provider: <your provider>
Other hidden rules are the management of enum and sip-codes lookup.
