Connecting the IP telephony: as simple as it could be!


 The first step you have already done — is to choose UNINTEL. Next, you only have to decide for the right tariff and that is not difficult, because our prices are the cheapest. After this, you will request a number (also a desired number is possible) and it is possible to keep your already saved contacts. After receipt of payment you will be sent a PIN code with which you can access the use of the VoIP communication with an web-enabled device of your choice.



Types of IP telephony


There are three most common types of protocols for data transmission:

  1. H323 — an H.32X series protocol, which also includes communication over public telephone networks. Its elements are: Terminal, Gateway, Gatekeeper and Multipoint Conference Control (MCU).
  2. MGCP — network protocol for the control of VoIP gateways, which transmits control information in the clear.
  3. SIP — creates sessions based on HTTP and SMTP, however, continues to evolve. This technology is very convenient to use as it assigns the number to the subscriber and not the location. In addition, the SIP protocol supports the transmission of sound and image.



Communication is possible with IP phone or softphone.


Selecting the type of your connection for IP telephony is the next step for trouble-free communication. Let us consider a few possible types of an external connection to an operator:


  1. To set a connection you need a software (softphone) on the PC provided by the provider.
  2. A phone number for IP phone. So: WLAN router or RJ45 IP telephone.
  3. Establish the connection using a gateway. A gateway allows the connection of two common phones.



After we took a look at the connection of IP telephony to an operator, let’s take look at three ways to set multiple external and internal numbers:


1. Connection of IP telephony using IP-PBX.

2. Connection of IP telephony using gateway, analog IP mini-PBX and conventional (analog) telephones.

3. Connection of IP telephony using IP-PBX and IP telephones. In order to increase the number of network ports, we connect a switch to the router and to the switch phones and PC.


With this type of connection, a great plus is the easy installation, but do not forget that the equipment is the most expensive.
We took a look at a small part of the possibilities.
