Description

Most organizations use a PBX for their voice communications. Clients and customers expect that services like music on hold, auto attendants, dial by name, and voicemail are available when they call a company.

SIP has become the de-facto standard in the Internet telephony world. A large and growing number of vendors offer great products that communicate using the SIP standard.

The pbxnsip PBX ties these two technologies together. The result is that our customers:

• Enjoy the look & feel of a PBX,

• Can connect directly to an Internet Telephone Service Provider or to a customer premises PSTN gateway,

• Can run their communications infrastructure solely on IP,

• Are independent from a single vendor, and

• Improve the experience of their callers.

The IP PBX will revolutionize telecommunication. And with pbxnsip, you can have it now for your customers.

If you want to get "technical" check out the competing products; find out if any other IP PBX product:

 

• offers built-in security using the sips, srtp and sdes standards,

• has a built-in session border contoller for solving NAT problems,

• can do call recording and paging,

• uses trunks to talk to gateways and service providers,

• can be installed in minutes,

• is available as Microsoft Windows service.

Private Branch Exchanges (PBX) are a standard component in today's businesses. They link handsets with the public switched telephony network (PSTN) and add additional services like auto attendants and voice mail.

Today, the vast majority of the companies have built up a data network as the central IT infrastructure component. Running an additional service called voice does not cause any headaches any more.

By adding a "virtual" PBX in the form of a software component, you can eliminate investments in proprietary equipment and operate only one infrastructure.

The pbxnsip PBX is the perfect product for the small- to medium-size enterprise. It offers all popular features of the PBX and maximizes the interoperability with existing vendors of SIP equipment. It works with most ITSP vendors that offer SIP services.

Architecture Overview

The PBX offers two ways to connect to external devices. First, you may register SIP user agents (UA), for example hard or soft phones, FAX or other SIP-compliant devices like conferences systems. Second, you may connect to the outside world via trunks.

The PBX supports several kinds of trunks. You may connect a regular SIP PSTN gateway to the PBX and terminate your calls to the PSTN through this gateway. The gateway does not need to support advanced features like transfer or dialog stage. See the list of PSTN gateways that we were able to test already.

The second way to talk to the outside world is an Internet Service Provider that offers you SIP services. There are a number of service providers available that give you global coverage at excellent rates. If you want, you can use several trunks at the same time, for example one trunk for local or emergency calls, the other trunk for long distance and international calls.
