Project description
In two different DCs, 2 identical Asterisk servers are deployed. You need to configure routing through a SIP proxy such as OpenSIPS, Kamailio or another solution so that in case of failure of the main server, the processing goes to the second one. In case of increasing the load, you need the possibility of balancing between the two servers. I'm ready to answer all the questions.
