UC540 Caller ID not displaying on handsets - only anonymous

[crusadecomputer]

Hi

We have just installed our 1st UC540 with SPA502G handsets.  Inbound and outbound calls work ok but when we receive an inbound call, we don't have the number calling ID displayed, we just get 'anonymous'.

Is there a quick and simple way to get the caller ID displayed?

Thanks

Andy

Start mentioning the type of phone lines you are using.

Hi Paolo

The lines are ISDN (BRI)

Then post "debug isdn q931" with "term mon" for an incoming call.

telent  to router and enter commands above.

Note, if you are the end user it is highly recommended that you involve a reputable consultant or UC certified cisco partner for any activity. Trying do-it-yourself can be very frustrating and not bring sure and quick results.
