Like to title says: Everytime someone call our fax machine the internet goes down.
I don't know if this problem started to occur when we upgraded the internet to 24/2 or when we implented our new firewall ( cisco asa 5505).
However, we have replaced the splitter (who split the analog from digital signal) two times, and replaced the modem two times (the modem comed from our ISP).
We have two different numbers. One for our telephone (IP telephone) and one analog to our fax machine.
I've called our ISP and told this problem like 6 times, but it seems like they can't solve it. I don't know if the problem is on their side, or on us.
Anyone have any idea what the problem might be?
