is "UPnP" turned ON for both MagicJack and the Router?

Do MagicJack's settings allow selecting Incoming Ports? More than one?

These serttings will affect the performance of MagicJack, as well as other programs (Skype, etc.).

Skype's "Tools" include these types of settings. See "Tools/Options/Advanced/Connections".

We were told to turn UPnP off for security reasons by NETGEAR. We have forwarded them manually, all of which are UDP. See below.

XXX = the dedicated ip address of Magic Jack
