Hello
I'm using a local VoIP gateway and a PBX to handle incoming PSTN calls. I'd like to forward unanswered calls to my cellphone via a VoIP provider, to avoid buying my own IP-GSM gateway.
Problem is, the VoIP provider I tried doesn't forward the original caller ID, ie. calls appear to come from my PBX instead of the real caller from the PSTN network.
Do you know of a good VoIP provider that will not rewrite the CID, and offers competitive prices to GSM networks in Europe?
Thank you.
