Hello, Newbie here! Have Kamailio set up on a 512MB VPS. Created a couple of users, registered with Zoiper and can call between them. I am looking for documentation to connect the server to other VoIP providers (Signalwire, Anveo, VOIP.ms etc.) to make & receive calls from the external network (DIDs) / PSTN Can someone point me in the right direction? Thanks in advance.
