How can an alternative port be used to pass SSL traffic on the UC540?

Client has an SA 520 connected to the UC540.  SA is taking care of all routing and firewall duties. VPN traffic is passed to the UC for remote 525G phones. However when the appropriate rule is configured to pass SSL (443) to the UC the firewall rule on the SA breaks SSL connectivity for smart phones.  There has to be an alternative configuration. Most companies use SSL secure mail for smart phones. The SMB support team has pretty much told me I am out of luck. The end result needs to included the following:

Smart phones need to work over port 443 (port forwarded to exchange server)

Remote clients need to be able to connect using Cisco VPN client (any flavor)

Remote 525G phones need to function remotely

Any help with this matter is greatly appreciated.
