[Freeswitch-users] Inter-domain connection

Hello, how do I realize an inter-domain connection with FreeSWITCH? I have two instances of FS. One in domain A and one in domain B. How can users in A call users in B (and vice versa)? Thanks in advance! Alois Komenda Fraunhofer-Einrichtung für Systeme der Kommunikationstechnik ESK
