No, it won't work, there's no '|' for alternative matches, and no parens
available for grouping, either. And your usage of char sets is off.
Try something like this:

_404NXXXXXX

_770NXXXXXX

_678NXXXXXX


as three separate extensions.

If you REALLY want to keep that as one extension, then you could:

_NXXNXXXXXX  =>  {
		Set(areacode=${EXTEN:0:3})
		if ('${areacode}' = '404') {
			<things to do here>
		} else if ('${areacode}' = '770') {
			<things to do here>
		} else if ('${areacode}' = '678') {
			<things to do here>
		}


OR, you could do it this way, also:

_NXXNXXXXXX  =>  {
		Set(areacode=${EXTEN:0:3})
		switch(${areacode})
		{
		case 404:
			<things to do here>
			break;
		case 770:
			<things to do here>
			break;
		case 678:
			<things to do here>
			break;
		}

This is, of course AEL code, and this stuff would be inside a context
construct...
