Hi All,<br><br>I need some assistance with a strange problem I'm having with Cisco Unified Personal Communicator.<br><br>I have a CUPC client running on the UC server network, users are able to login and see the presence state of other users and IM other users. The other client is connected to the phone, in the data VLAN. Users are not able to log onto this client, when the same user tries to log into the CUPC client on laptop connected to the phone they get an error message 'Unable to connect to network, Please check your network connection'.<br>
<br>This is a new server running CUPS 8.x and CUPC 8.x, currently in the lab and both incoming and outgoing ACLs have been upset to allow ALL. I should also mention that the topology is that the server and the phone are in different locations, the phones register via a simulated WAN and both CUPC and CUPS have IP connectivity both directions and there are no ACLs on the routers.<br>
<br>Any assistance would be greatly appreciated. <br>
