This is not a problem of OBI200 but only of this one provaider
This problem is generally known to most and concerns Asterisk.
So far I haven't been able to find a solution.
However, since AA is working properly, I have the following question:
Is it possible to set AA so that the caller does not have an announcement or does not have to press 1 for AA to transfer to my mobile phone.
All incoming numbers, outgoing from AA only one, my cell phone.
