Use 3CX softphone

can I use Voicent IVR Studio directly with my 3CX softphone configured with a sip number?

If you have a softphone working, you can get Voicent software working also. In fact, you do not need any softphone in order to use Voicent software, which can act as a softphone or softphones.

Almost all softphones are based on SIP, which is the standard for Voice over IP. To configure Voicent software, simply use the same configuration you have for a softphone. You could download the software and give it a try. For details, please see Using SIP for Voicent software
