[Asterisk-Users] Setting variable for a context for all extensions?

[Mark Wormgoor]

Hi,

Is it possible to set a variable for a context for all extensions?  I 
haven't been able to find it.  I want something like this in 
extensions.conf:

[from-iaxfwd]
exten => .,1,RING=r3
exten => 123456,1,Goto(from-pstn,s,1)

[from-internal]
exten => .,1,RING=r2
include => ext-local

[ext-local]
exten => 1,1,Dial(Zap/1,${LONGTIMEOUT})
exten => 2,1,Dial(SIP/2,${LONGTIMEOUT})

But how do I do this?  I want to change the ring depending on the 
starting context.  The above doesn't work.

Kind regards,

Mark
