I guess I should have tested the sipira ata 1000 for this dial plan that works every time for the ip500.
exten => _82NXXNXXXXXX,1,Dial(dahdi/1/www82,15,mD(${EXTEN:3}))
So why does the sipira ata1000 not want to skip over the *82 when I dial it with the number?
Feature to enable *82+number that I do not see in the sipura to make it work with this string so whats left to do?
