asterisk users - Jun 2005 - Busy, differences between SIP and Zaptel(bristuff)

Hi all,


a lot of my snoms are being called with this macro:

[macro-ohne-AB]
exten => s,1,DBget(temp=UML/${ARG1})
exten => s,2,Goto(default|${temp}|1)
exten => s,3,Dial(${ARG2},600,g)
exten => s,4,SetVar(PRI_CAUSE=17)
exten => s,5,Hangup


[default]
...
exten => 77,1, Macro(ohne-AB,77,SIP/snom8556)
...


When a call comes over QuadBRI in and the called phone is Busy the caller gets a
Busy. That is fine. When another snom is calling a busy snom, then it gets an
"forbidden".

When i change Hangup to Busy the call "snom" to "busy snom"
is OK. Incoming ISDN calls get silence, then after 10 seconds an congestion.
That is ugly.

What is the right way to make a busy for Incoming calls (QuadBRI) and internal
calls (SIP to SIP).
