Voxalot / SIP Broker Support Forums - View Single Post - What is the "Inbound CID Pattern" for "no caller ID/number"?

I find it varies with your DID provider. AFAIK, an incoming SIP URI call always has a sip:something@provider.org address (or sip:something@0.0.0.0). Figure out what the caller id is reported as in in your software/sip device--I find unknown is typically sent as "0" (the numeral zero) with Voxbone--and enter a generic rule for it.
