The T21P phone in your side is an old product.
It has different hardware, and I check, it can't support VPN.
Sorry about this.
Hi,

If in case you're interested in a CTI solution that will integrate your CRM to your phone system, you can check out a company called Tenfold. They offer features such as click to dial, automatic call logging, easy note taking and task creation, screen pops on inbound and outbound calls, new lead/contact creation when no matching records, support for cases/opportunities and advanced analytics on the backend.
