Thanks for the info. So nothing in the Asterisk Phone book.
The inbound route settings are: CID Lookup Source->Source: None, and Superfecta CID Lookup->Enable CID Superfecta: (no checked), Scheme:ALL.
I don't think we were ever using CID. How can we check the DB for the cached record and clear it?
We've noticed recently that we're getting CID on multiple PBX servers we have (all with Anveo Direct as the provider), so they are probably being passed from the trunk. Is there a way to set the trunk/peer settings to disable this or at least make a permanent modification of certain CID's that are wrong (probably by editing the Asterisk Phonebook?)
Update: I made an Asterisk Phonebook entry for the problem number, then added an "Internal" Caller ID Lookup Source under that module, and then selected that source on the inbound route for the receiving sides DID. This is now overriding the CID that seems to be coming from Anveo Direct. The only problem with this is that you have to go to each inbound route and change the CID source to the Internal one made. I can't find a way to apply it to the entire trunk.
