Hello! I would like ask you how can I prevent secondary registration of IP Phone. If I register 2nd phone, they both will be registered and both can make outgoing calls. Incoming calls gets only one of them (in my case first one). So I would like prevent secondary registration. I could send XML push for second phone with text message like “this username is busy now”, but asterisk anyway accept this registration. By the way they (IP phones) shouldn’t binded to static IP. Just need some way to tell second IP phone “denied” on registration if this SIP is ON already or sort of.
Can you help me?
P.S. I do not use Users, only SIP configuration. Phones model “Fanvil C62”
