Hey, no bubble to burst - I'm always up for finding an easier way. I
didn't realise that just by checking the existence of a pair it stored
it in a variable.
OTOH it *is* more yeuch to read. All of those $ { [ are soooo easy to
misplace, and sooo easy to misread and not find the problem.
And it is only 3 more lines of code :)
if no-one wants the patch, I'm more than happy to go with this method.
Thanks.
Julian.

There are often times that I want to read a DB value from the dialplan,
and if this family/key pair does not exist, set it to some default value.
for example:
1234,1 => Set(EMAILADDR=${DB(x/y)}
1234,2 => GotoIf($["${EMAILADDR}" = ""]?3:4)
1234,3 => Set([EMAIL PROTECTED])
1234,4 => NoOp(${EMAILADDR})
1234,5 => Hangup()
I hate to burst your bubble, but what's wrong with using the DB_EXISTS
dialplan function?
exten => 1234,1,Set(EMAILADDR=
${IF($[${DB_EXISTS(x/y)}]?${DB_RESULT}:[EMAIL PROTECTED])})
Obviously it's a little harder to read (especially when all placed on
one line), but it's already quite easy to use without adding more code
to Asterisk.
