Dial timeout

Hi,

in my dialplan is a timeout of 120 seconds set. If I test it, it is about 130 seconds.

Answer();
Dial(SIP/1002,120);
Playback(vm-goodbye);
Hangup();

Where is the problem?

I tested it now on another server. There is the problem too.

I think it’s a problem from my provider (1und1). If I use sipgate it works fine.

Any idea?
