they are both sip trunks.
I have two number from that provider.
each number is one separate sip trunk, with username and password.
I have two phones, one for each number.
If I use two askozia boxes, everything is fine, but I want to use only one.
So I setup that number A goes to phone A and number B goes to phone B, which works fine too.
But it doesn't work if i want to use extensions.
So if i configure:
Number A with extension A2 to phone A and number B with extension B4 to phone B, I receive "Forbidden" on one phone.
I cant reach it anymore, with extension or with main number.
