Re: [Serusers] SER & Asterisk in a non-routed environment

thanks for that, i'll give it a try. Furthermore question: What if i have another customers network, say 192.168.20.0/24 connected with it's own gw-box running its own instance of ser. How would * on an incoming call know, where to forward it to? greeting from germany Lars Klaus Darilion schrieb: > Yes you can do it.
