I've installed Nokia Intellisync Call Connector on a Nokia E51.
The Nokia E51 is registered (SCCP) on a Cisco UC500 system and works fine.
There is only one problem! When I've a call on the Nokia E51 en try a transfer (full-consult) to some other internal number the transfer fails. I get a transfer reject message on the Nokia E51.
I hope there is some solution for this problem. I've read the Nokia Intellisync User Guide and it seems to be possible.
