Also, caller ID only shows numbers, no names - normal?
You didn't mention if this is a GV acct or a sip acct. If you are talking about a GV acct, then yes, they only pass CID number. If you want a work around to get CID NAME+NUMBER, look up the Call Centric thread started by our friend pc44 for an excellent explanation on how to set it up.
Voip service providers may not all offer the CID NAME especially if the call is coming over from the PSTN side, as they need to find the number in a 3rd party database in order to pass that NAME. Some SPs offer it (free or at a premium). Calls originating and terminating over voip (sip to sip calls), should pass CID NAME, as it is built into the sip protocol.
