In sip.conf, how can I define that only IP phones from 192.168.0.0/24 network can register with specific user? The thing is that I can't use password and I can't use host=ip.of.my.phone. And I have to be sure that no one, from Internet will register on my * like that user. So, please tell me how to do this? -- Tomislav Parcina tparcina#lama.hr
