Configuration of the Cisco CME/UC500 for CSTA is required before connecting.
TCP: 5060 - Note: the PBX will make a reciprocal connection back to Go Connect Server. This may require specialist firewall support/configuration. Operation is recommended for LAN use only.
The Cisco Call Manager Express / UC500 connects onto the LAN via one of the RJ45 sockets on the front of the PBX. The local IP address and other network settings are set through the HTML-based programming interface. Advanced configuration, such as is required for CSTA / XML configuration is normally done via the telnet interface.
Firmware Requirements (for new installations):
15.0(1) or later
