O2Run Systems

 O2RUN IP PHONE

 

​O2Run IP phone uses voice over IP technologies allowing telephone calls

to be made over an IP network such as the Internet instead of the ordinary PSTN system.

Calls can traverse the Internet, or a private IP network such as that of a company.

 

The implementation of an IP telephone system in a business requires the use of a very

specific type of phone: the IP Telephone.

 

The overall hardware may look like a telephone or mobile phone. A VoIP phone has the following hardware components.

• Speaker/ear phone and microphone
• Key pad/touch pad to enter phone number and text (not used for ATAs).
• Display hardware to feedback user input and show caller-id/messages (not used for ATAs).
• General purpose processor (GPP) to process application messages.
• A voice engine or a digital signal processor (DSP) to process RTP messages. Some IC manufacturers provides GPP and DSP in single chip.
• ADC and DAC converters: To convert voice to digital data and vice versa.
• Ethernet or wireless network hardware to send and receive messages on data network.
• Most IP phones have a PC data jack on the phone. This allows your computer and phone to share one data connection.
• Power source might be a battery or DC source. Some VoIP phones receive electricity from Power over Ethernet.
