UC520 Caller-ID problem

Hey

We have a UC520 via analogue line.
Now we want to switch to a SIP trunk and this works.
Incoming and outgoing calls arrive, only when we call out does the number come through as an anonymous to the recipient.

He seems to be calling out the number of the trunk's sip user name and this is not a valid phone number.
When I set the caller ID in CCA, the UC520 also tries to use this as the username for the trunk, with the result that the account is blocked due to incorrect logon.

The sip trunk is from WeePee (Belgium)
