Can't get call forwarding to a cell phone working. Have the number in a speed dial bin. In cos 3 have follow external call forward set and the trunk to trunk options set. In form 4 have Incoming to Outgoing call forward set. In form 30 have devices allowed.

The phone accepts the call forward programming. Call never forwards. If set form 19 no answer or busy to the speed dial that does not work either. What does work is when I program one of the DID numbers to go to that speed dial bin the inbound call does route to the cell phone. Inbound and outbound is via a PRI.

Any suggestions??
