We've configured SSL VPN onto an alternative port on our ASA (DTLS remained on 443) and now i've an issue connecting the IP Phone via Internet onto our CUCM 9.1.
In logfile i can see access denied messages on TCP/443 and so it looks like the Phone tries to connect to the standard port - in the Group URL i configured the URL including our alternative port.
Is it possible to configure the alternative VPN port somewhere on the IP Phone or on CUCM?
