Dear friends,
I want to use a couple of two VoIP phones according this schematic because SIP protocol is blocked. I heard by using RouterBOARD I can Tunnel thru Internet and these VoIP phones can call each other.
SIP Phone – Mikrotik RouterBOARD – ADSL Modem (in country 1, invalid dynamic IP) – INTENET – ADSL Modem (in country 2, invalid dynamic IP) – Mikrotik RouterBOARD – SIP Phone
I am very newbie and I don’t understand these technology. May I ask to help me know more about it and how these things work?
