I have a few UC520 installations in Perth now and none of them seem to bring up the caller id information on any of the FXO trunks. The Called ID works well on the sip trunks.
Is there something that is missing from the factory configurations from CCA to get it to work?
Any help is appreciated.
Assuming the boxes were configured with CCA, this should work automatically. If you have configured the boxes uses CLI, make sure you have 'caller-id enable' and 'cptone AU' configured under the corresponding voice ports.
Also, I know this sounds obvious, but I have had quite a few cases recently where the telco swears blind that caller id is enabled on the FXO lines for the first three or four times they get asked, only to finally 'discover' that it has somehow become disabled on the fifth or sixth request. If you are sure of the config, it is always a good idea to plug in a caller-id enabled handset or a butt set to prove the point.
