We have our Asterisk server on cloud and recently the government blocked SIP from non-whitelisted IP’s. We have whitlisted IP’s for our office but now due to Covid19, most of the users are working from home for which we cannot get whitelisted IP’s. Currently we are using VPN but are having issues in that.
I was thinking of configuring another asterisk server in office so that users can get registered on this server and route traffic on cloud server but not sure how exactly that would work.
Another aspect I was looking into was Kamalio server but I’m total noob with Kamalio.
May be adding TLS would work, this should be simple but thats not working for me.
Can anyone suggest best possible alternative?
