I'm having trouble getting CID to work with my SPA 3102. I'm using SIP to call out (Voipbuster) and using the PSTN line to receive calls. When I switch off the SPA 3102, CID works fine on my incoming calls. I think I've tried every setting I think off (visited many forums):PSTN Ring Thru Delay, Caller ID Method, PSTN CID For VoIP CID = Yes, went back to the factory default, installed the lastest firmware 5.1.10, etc. In the info tab everytime the Last PSTN caller only shows a , .
I've captured some logging information of an incomming PSTN call, see attachment.
Any ideas on how I can get CID to work, thanks.
