I think the n's should all be 1's, like so:

exten => 6140000000/_702XXXXXXX,1,Goto(context1,s,1)
exten => 6140000000/6149999999,1,Goto(context2,s,1)
exten => 6140000000/6149999998,1,Goto(context3,s,1)
exten => 6140000000/6149999997,1,Dial(SIP/7777,25)

The 'n' priority is used for subsequent lines (after the first) in the same
extension, but the first one for each extension should be 1.

I suggest you don't use _X! or _X. as a pattern, until you fully understand
the security risks.  In the asterisk-1.8 tarball, there's a file called
README-SERIOUSLY.bestpractices.txt that explains it all.
You should read that before you do anything.

You have an example for NPA only in the line that handles area code 702.

Similar for NPANXX:

exten => 6140000000/_614999XXXX,1,Goto(context,s,1)

This is all covered quite well on the voip-info wiki:
