[asterisk-dev] Quoting in AGI data

[Alistair Cunningham]

Can someone from Digium please definitively say whether AGI data which 
contains spaces should be quoted or not? I.e. which of the following 
methods are correct?

A. SET VARIABLE CALLERID(name) Test User

B. SET VARIABLE CALLERID(name) "Test User"

We've found that some Asterisk machines seem to produce the following 
incorrect header on an outdoing SIP Dial() after using method A:

From: "Test" <sip:101 at 1.2.3.4>;tag=as6cf271a2

but do not do it for method B, while other machines do it for method B 
but not A. We have been unable to determine why there's a difference in 
behaviour.
