You are right, it looks like the backslashes are being silently
swallowed, but adding extra ones doesn't help either :-)
It cannot even match the backslash itself (\\). By the way, using your
suggestions, one should type "\\\" to match a backslash :-)
I had to do something messy to get this to work in the dialplan:
exten => 1,n,Set(PLUS=\\+)
exten => 1,n,set(INNAT=${REGEX("^${PLUS}" ${ATELNO})})
exten => 1,n,gotoif($[${INNAT}] ?visint)
Now admittedly I had a whole lot of other things going on that
probably made it harder than it had to be.

I came across an issue where the user interface I was using (FreePBX?) to enter
expressions was silently swallowing backslash characters (this wasn't regexp,
but my dialplan had to add a SIP header with a semicolon in - that was falling
foul of the comment character matching for the user interface, so I had to
escape it, but that was being stripped elsewere!)

The regexp expression "^49\+" works. Does Asterisk have problems
matching the plus at the beginning of the string, or am I escaping
something incorrectly?

That's because you don't dial a + you dial 011 here in America, the +
is meta for insert you international dialing prefix here.
That doesn't much explain why the regexp doesn't work. If you're
dialing from a softphone, for instance, and dial a +, it comes through
as a +. It's up for the server to decide what to do with it. If you
can't match it and therefore convert it to the appropriate international
dialing prefix, that's a problem.
Think globally. :) Not everyone wants to require their customers to all
dial 011, or 00, or 001, or any number of alternate international prefixes.

When receiving calls, I have a number in RURI and "From" field exactly
in this international format (with plus) and have to transform it to the
usual 0049... That's why I have to match the plus.
