I had configured UC560 via Telephony configuration wizard in CCA and I assigned PPPoE configuration too. After saving the configuration I was able to get the internet connection from UC.But after a day I removed the Dialer0 interface cable and reconnect it again, there is no internet connection. But but in this case I checked the interface status and it is showing Dialer0 unassigned and port is Up also.That same connection I checked with Linksys broadband connection by providing Internet account username and password which I assigned inside UC and I was able to get internet connection.
Please suggest any additional configuration I have to do inside UC to get internet connectopn back.
I would plug the cable back into the WAN port and then log into the CLI and do a "shut" and then "no shut" on the dialer0 interface.
Your configuration is fine and is a standard setup, not sure why though it is coming up as unassigned.
As a last resort though, you may need to give the UC a reboot and see if that brings up all the interfaces properly, such as any virtual ones as well (Although you shouldn't have too).

Yes It is working .......I done the configuration via CLI and put the access list 104 I edited the access list to permit all to all. now UC is sharing internet.I tested by shutdown the UC and restarted it is working fine.
