TAPI is one of those die-hard standards from the 90s. Originally designed to deal with hardware installed in the PC, it has evolved over time into a more virtual piece of software that connects the user programs running on Windows with the devices that make phone calls.
Not much of a surprise, the PBX world has widely adopted TAPI. Almost all vendors of PBX systems offer a TAPI service provider that may be used with their PBX. This is like a device driver for the PBX.
Also snom ONE has its own TAPI service provider (TSP). While the first versions were very basic, the latest one now also offers incoming calls. This is an important step forward, because a lot of CRM tools also offer a bridge to TAPI; thus essentially making the incoming call pop-up possible. But also for outgoing calls the new TSP has enhanced functionality, so that calls can be cleared even though the user has not even picked up the phone. Also, we had to find out that not only for SIP connections, but also for CSTA the internet can be unreliable and the TSP needs to reconnect in case that the connection got lost.
Like before, we offer the TSP for 32 and 64-bit systems. Because of its origin from the 90s, you need to pick the right one for your Windows operating system as there are dependencies in it.
