3. A system for transmitting voices over a
distance using wire or radio, by converting acoustic
vibrations to electrical signals.

4. Alexander Graham Bell was awarded the first U.S.
patent for the invention of the telephone in 1876.
Elisha Gray, 1876, designed a telephone using a water
microphone in Highland Park, Illinois. ... Thomas
Edison invented the carbon microphone which
produced a strong telephone signal.

5. Conversation is interactive communication between two or more
people. The development of conversational skills and etiquette is an important part
of socialization. The development of conversational skills in a new language is a
frequent focus of language teaching and learning.
A conversation over the telephone. conversation - the use of speech for

6. The term call recording means to record a telephone call or other audio source.
A call recorder is the hardware and software that tap into a phone line (usually multiple lines or
channels) and records or monitors those calls

7. Though no trace of a working paleophone was ever
found, Cros is remembered as the earliest inventor of a sound recording and
reproduction machine. The first practical sound recording and reproduction
device was the mechanical phonograph cylinder, invented by Thomas Edison in
1877 and patented in 1878.

9. Points X and Y in the circuit are connected to the telephone lines. Resistors R1 and
R2 act as a voltage divider. The voltage appearing across R2 is fed to the ‘MIC-IN’ socket of the tape recorder.
The values of R1 and R2 may be changed depending on the input impedance of the tape recorder’s ‘MIC-IN’
terminals. Capacitor C1 is used for blocking the flow of DC.
The second part of the circuit controls relay RL1, which is used to switch on/off the tape
recorder. A voltage of 48 volts appears across the telephone lines in on-hook condition. This voltage drops to
about 9 volts when the handset is lifted. Diodes D1 through D4 constitute a bridge rectifier/polarity guard. This
ensures that transistor T1 gets voltage of proper polarity, irrespective of the polarity of the telephone lines.

10. VoIP or Voice over Internet Protocol is one technology that uses
the internet for every operation. In traditional call recording methods, calls were taped and
stored manually. This type of data storage was only half as good as it was exposed to
physical damage and regular wear & tear. In VoIP-based recording, all the calls are auto-
recorded and saved on the cloud space. The database is secure from physical damage and is
easily accessible from any part of the world.
How is VoIP call recording different from its traditional method?

11. How does Call Recording work?
The mechanism of auto-recording of calls can be explained in a below-
mentioned manner –
You direct your VoIP service provider to activate this facility for your outbound
and inbound phone calls, once activated, all the calls coming and going from
your on-site extensions will be auto-recorded.
All the recordings will be saved on-cloud, and the admin will have access
details. Records can be downloaded and played multiple times

12. How many calls can you record?
All the inbound and outbound phone calls are
automatically saved in the call logs and are available for
download up to 90 days. You can download these
recorded audios and save for your reference in the future.
You can record 100,000 calls per account – be it outbound
phone calls or inbound ones.

13. Types of call recording
Call recording can be done in three major ways –
1 – Hosted: In this type of call recording, you don’t use the equipment on your worksite.
Instead, everything is managed by your VoIP service provider. You only pay a monthly rental for
their services, and they take care of the rest of things.
2 – Software-based: In this type of call-recording, all the needed hardware and software are
installed and maintained at your site. You connect all your data-driven devices used for making
outbound and inbound phone calls with the software, and it records everything.
3 – Hardware/Appliance: In this category, calls are being recorded by using a rack-mounted
appliance attacked with your VoIP equipment. The device is directly connected with all your
VoIP equipment through LAN cables and functions on the web.

14. Do you need to pay for the call-recording facility?
Call recording facility is the part of your hosted VoIP subscription, and you
need not pay for it separately. They will look after the management and maintenance,
keeping you free from all the tensions. However, if you are using a software-based recording,
then you may have to bear the maintenance cost from your end.

15. How can you activate the call recording?
If you are using a personal virtual phone number, use the option for turning call recording ON/OFF
in order to activate or stop recording. This option must be easily visible to you in the interface. It
will be activated for the particular call. You can also activate the recording feature with the ‘look
back’ technique where the entire call will be recorded, and you will get the recording once the call
is finished.
However, you need to contact your VoIP service provider if you want to activate call-recording on
all of your work-site extensions. Some of the VoIP numbers come with auto-recording.

16. The best device to record telephone
conversation ?
The PR200 is the ultimate recording device because is can record both cell
phone calls and function as a regular handheld digital voice
recorder. The PR200 can take care of most of your recording needs. ...
Most phones have bluetooth capability including iPhone, android, all
smart phones, and basic cell phones.
