VOIP capable PBX integration

We are currently using a VOIP capable PBX system provided to us via Fonality. I am interested in the following: Will your product integrate with a VOIP PBX via TAPI and does it require a SIP acount?

Voicent release 6 supports 1) Voice modem, and 2) VOIP through Skype.

If you are using Skype, you do not need PBX system. All you need is internet connection.

You can use voice modem based solution for any PBX system, as long as the PBX system supports analog telephone line. You can connect a voice modem to an analog phone line to make phone calls.

We are planning to support SIP. But this feature is not available in the current release.
