Hey guys,
Yesterday our IPO was hacked. They managed to get through one of the remote workers. And made some 300+ calls to various countries some of which I didn't know existed.
We really need the remote workers. Our employees use them natively on their android phones.
Currently we have the 5060 port disabled by firewall (Mikrotik router) which sits above the Avaya.
How can we secure the VOIP? I can't seem to find anything online?
