SIP and SIP Client

SIP, that is Session Initiation Protocol, creates and disconnects multimedia calls between two or more parties. SIP can manage text, video and audio data. So callers can chat, make video and audio calls and organize instant message/audio/video conferences.

A SIP client is actually a device or a software used for dialling. These tools can be converted from a normal machine to a SIP client with a simple registration and connection to a SIP server, the Ozeki Phone System. Any computers or new generation devices can be converted to a SIP client. The devices (PDAs, tablet PCs, iPADs, smartphones, etc.) must be able to use the Internet for communication:

How to Have a SIP Client?

In order to convert your device into a SIP client, you have nothing else to do but follow these few easy steps:

  • check your device whether it is capable of using the Internet for communication
  • have an Internet subscription - with the proper bandwidth
  • subscribe to a VoIP service provider (obligatory)
  • download and install the Ozeki Phone System software on your device (in the case of IP phones, you will not need to install any software. Just configure it with giving the user data)
  • in the menu, choose Connections / Extensions / Install and give the user data - now you are registered and your SIP account is created
  • give these data to the given device, and the IP address of the place of connection
  • repeat the last point with every device you intend to join to the system

After having done these, your SIP clients are set. You can make and receive phone and multimedia calls within the business or anywhere in the world.

How to Use SIP Clients

Using SIP clients is just as easy as using any telephones. When you use SIP for calling, it does not differ from the normal calls, but it is managed through the Internet.

SIP devices communicate through SIP connections. They use the same protocol, so their communication will be standard. With the standard communication, they can connect and communicate with each other without limitations.

With your Ozeki Phone System SIP server you can chat, have voice and/or video calls and organize chat/voice/video conferences. These all can be done in the same time within the business.
