Hi all,
I´ve noticed a problem with my sip devices.
All of them work for a couple of days and then they just stop working.
After a reboot, or swapping from router mode to bridging.
all starts working again. 
I´m getting a bit crazy of this I tried to open all ports but no better results yet.
I upload screenshots of all the routers on my network.
I have 1 public IP for the all the network and 4 people are using thise sip devices
The problem is probably that I don´t know how to open these ports properly on the mikrotik…
I hope someone here can explain me how to open them properly using winbox.
Isn´t there a simple way like on for example a Cisco router to open these ports?
And I´ve found this topic:
http://forum.mikrotik.com/t/how-to-open-a-port-using-winbox/23823/1
Here they tell this person that ¨most¨ ports are opened by default.
So what is my problem then?
Ports that need to be opened are:
5075-5076 TCP/UPD
16384-16482
Many thanks.
