Cannot forward a voicemail to another mailbox using UCP in ver 15

We cannot forward a voicemail to another mailbox through ucp in ver 15…it shows a drop down box and only lists mailboxes i have allowed access to on my ucp ie the ones that i can create widgets for… i need to be able to forward the voicemail to any valid mailbox on the system. In ver 13 we would just type in the mailbox number to forward to and now ver 15 has a drop down box but does not allow you to edit or enter a mailbox number and only displays the mailboxes i have delegated permission for.
