This is one possible solution:

^\+?(?:\d-?){9,14}\d$

Explanation:

^          # anchor the pattern to the beginning of the string
\+?        # optional literal +
(?:\d-?)   # a digit, followed by an optional hyphen
{9,14}     # 9 to 14 of those
\d         # another digit (to make that 10 to 15, and disallow hyphens at the end)
$          # anchor the pattern to the end of the string
