I just switched from Callcentric to Vestalink -- partly because I was experiencing issues on incoming calls and also because I needed outgoing at a reasonable price due to XMPP being discontinued on GV.
When I receive an anonymous call -- either to my GV number and forwarded to my Vestalink number - or called to my Vestalink number directly -- the phone attached to my Obi rings and displays nothing on the caller ID. (My phone will display "Unknown Caller" for missing CLID info, or "Private Caller" for numbers intentionally blocked normally).
In the call history of the Obi, it shows the caller ID as "Anonymous" - but for whatever reason, that is not making it to the phone. Is there any way I can fix this?
