The easiest method to configure Voicent software to use a PBX system is through the PBX system's IP extensions, which are used for IP phones or softphones. Today, most major brands, such as Cisco, Avaya, Mitel, etc, all support IP extensions.

Before you start, take a look at your PBX connections. If it is using a SIP trunking service, such as Broadvox or bandwidth.com, then you should directly

The following steps are generic instructions that apply to any PBX system. For specific PBX system, please click the following link: Cisco Avaya, Mitel, Asterisk, Shoretel, Talkswitch. We are going to add more info for systems such as Trixbox, Switchvox, and more.

The first step is to configure an IP extension (or extensions for multiple lines) for an IP phone or soft phone on your PBX system. The exact steps depends on your PBX system. Please check your PBX admin manual for details. The IP extensions, sometime also called SIP extensions, are different from traditional extensions that are used for physical line connections.

The extension should contain connection information, such as extension number, user name and password. Along with the IP address of the PBX system, the information (a.k.a. SIP credential) allows software programs like Voicent to connect to the PBX and use the extension.

Once an extension is configured, you can test it with an IP phone or a soft phone like X-lite. There are many free soft phones online and one of the most popular one is X-lite. Many of the PBX user and admin manuals, as well as many online content, contain sections on how to configure for X-Lite. All these steps described for setting up X-Lite should also apply to Voicent software, since it also acts as a set of soft phones.

Enter the SIP credential information to the soft phone's setup page. For X-Lite, it is under the "SIP Account Settings". If the SIP information is correct, X-Lite should start and show it is connected. Try to make a few test calls and make sure audio works both ways.

Please note the above two steps are independent from Voicent software.

Once X-Lite is running and working, Voicent software should be working too. All you need to do is use the same SIP credentials to configure Voicent gateway. To enter this information, open Voicent Gateway, select Setup > Options > SIP tab, and click the Add button.

If you want to setup multiple lines, you need to repeat the steps to create additional extensions.

Please note that Voicent software does not need extra software (like x lite softphone) to make VOIP calls. Voicent software is configured as a softphone when used with a VOIP service.
