Firstly, make sure the GS phones are of a relatively new hardware revision 
and have the latest firmware loaded...

   Program-- 1.1.6.16    Bootloader-- 1.1.6.5

is a current "good" version for GXP phones.

This is wrong - you need :2 to skip over the 2 stars.

You might want to try:

   exten => _**.,1,Pickup(${EXTEN:2})
   exten => _**.,n,Hangup()

Which is what I use and it works just fine.

And one other thing to remember if it's relevant for you, is that 
different phones send different things - eg. Snoms send *8 then the 
extension number, so putting:

   exten => _**.,1,Pickup(${EXTEN:2})
   exten => _**.,n,Hangup()

   exten => _*8.,1,Pickup(${EXTEN:2})
   exten => _*8.,n,Hangup()

Somewhere covers both cases.
