[Asterisk-Users] No busy detection

[Jan Mvrn]

I have some problems with busy detection and SIP. When I'm making a phonecall (out or internal) and someone else is calling me, the phone (Snom200) is ringing and leaving the first caller (no difference if I call someone or if someone  calling me) in the background waiting. It doesn´t hang up the first call but the second one is overriding the first.

Is there anyone that has experienced the same problem and can help?

regards,
