Hi, I've been struggling around with my kamailio configuration.
I've managed to install kamailio on Ubuntu Server and configured 2 clients,
I've registered them in Zoiper to my server. They can call each other, but
are unable to talk. There is no audio heard. Ports opened on the router are
20000-30000 UDP and both TCP and UDP for 5060 and 5062. Are these ports
correctly opened? Thank you.
