How to connect PBX to outside world? SIP trunk management
This article is a brief introduction about connecting a PBX to the outside world in relation with Ozeki VoIP SIP SDK. After reading through this page you will be fully familiar with all the essential terms concerning PBX connection.
How to connect with the outside world? Why is it useful?
Please be informed that PBX development support is available in Ozeki VoIP SIP SDK from version 10.0 If you use an older version, please update your Ozeki SIP SDK. You can download the latest version from the download page.
The PBX is connected to the Internet through standard protocols like any other device or program. SIP messages are usually sent as TCP or UDP packets through the net (with the help of Ozeki VoIP SIP SDK, you can even set the transport type).
The PBX can also be connected to the PSTN (public switched telephone network). This is an other way to connect the PBX to the outside world. For this purpose you only need to have a special adapter that registers to the PBX with a SIP account and from that point the PSTN network works as a single VoIP end point.
An ATA (Analog Telephony Adatper) usually takes the form of a small box with
a power adapter, one Ethernet port, one or more Foreign exchange station (FXS)
telephone ports (i.e. rj12 receptacles) and may also have a Foreign exchange office
(FXO) link (i.e. telephone, pbx, or answering machine). Users can plug one or more
standard analog telephone devices into the ATA and the analog device(s) will
operate, usually transparently, on a VoIP network.
An ATA is connected between an IP network (such as a broadband connection) and an existing telephone jack in order to provide service nearly indistinguishable from Public Switched Telephone Network (PSTN) providers on all the other telephone jacks in the residence.
If the PBX is able to connect outside networks, that means it can handle analog devices as extensions, so ordinal telephone devices will be able to register and communicate via the system.
