The web page port has nothing to do with the Micro PC Client. That port is only used
to access the RRC via a web browser, for example: 192.168.0.224:8080.
The Micro PC Client only speaks to the radio RRC through the SIP port, so this is
what you need to put into the software. No TCP port number is necessary, only
use the radio's dynamic DNS or external IP address without a port number (like :8080)
at the end.
