Try to change 15 to:
15 _5 0207xxxxxxx Sipgate Yes [Edit] [Delete]
(just forget the ${EXTEN:1}) and be sure that 0207xxxxxx is what sipgate expects to be dialed.
Are you sure sipgate does not expect something like 44207xxxxxxx just like you are dialing in voipcheap? If it is, just change 15 to dial this and not 0207xxxxxx)
