What is a SIP phone in Singapore?

Know more in detail about SIP phone protocol and two types of SIP phones.

Basics of SIP Phone

SIP Stands for Session Internet Protocol. In Simple terms, SIP phone stands for a phone system which connects through the internet. While in conventional telephony, you need copper wires installed to be able to connect to the phone, there is no such requirement in SIP protocol. You can link to telephone system even by using mobile internet.

A key thing to note here – Even if SIP connects over the internet, it can make and receive calls to any landline or to the mobile number. SIP is not like or any other calling app, which is typically restricted on calling to people who are using that app.

SIP Phones are of two types:

  • Hardphones or Deskphones
  • Software SIP Phones

SIP hard phone

These are hardware phones which look like any other old type phone. See the photo on the side and you will get an idea. The picture here is of a Cisco SIP phone. While it looks much like conventional phone, it is connected to a RJ-45 (Ethernet cable) jack just like your computer. This way the phone is able to connect to the internet to make or receive calls.

It is a general experience that hardphones are able to give the best voice quality and call completion compared to softphones. This is because most of the time these are connected via a LAN cable (So work better than wireless) and these have dedicated circuits for voice processing.

If your job is deskbound, then we will recommend you to consider a hardware phone as your primary SIP phone. However for this phone to work, you must be connected to the internet.

Soft SIP Phone

As the name suggest, this is a software program phone, that can be installed on your computer, laptop or on your mobile phone. Many free software SIP phone clients are available on internet and in Android and iOS marketplace. A sample of this is shown on the picture here.

SoftPhone Benefits

The Key benefit of the software SIP phone, is that it is completely mobile. Your phone in this case travels with you. If you have installed it on your mobile phone, then it sits in your pocket, and anytime a call is routed it will ring on your phone which you can attend to.

If the SIP phone is installed on your laptop or desktop, then you can communicate and make / receive calls while working on your PC. Moreover the data from such software can be integrated with other applications like CRM or dialer software.

Have both Hardware as well as Software SIP Phone

Certain setups will allow you to do login to SIP phone from two instruments. In that case you may have both a hardware as well as software SIP phone. So when you are in the office, on your desk, you can use the hardware phone, but while on move, you can use same number and extension using a software sip phone.
