I have a questions regarding the firewall rules for Asterisk VoIP server.
I have a restricted access to UDP/TCP port 5060, which seems to be blocking calls.
I want to make sure that my VoIP Server is not hacked, or misused. So, if anyone can let me know which ports needs to be open to all, I would really appreciate it.
Any help on this is very helpful.
Right now, the Asterisk server has the following access control.
USD/TCP port 5060, restrictive access.
UDP ports 10000:20000, global access for RTP media.
Thanks for all those who will contribute to the solution of this problem. I am very sure this will be useful to a lot of admins out there.
BTW, I have been referring to these Links to solve some amount of problem.
