More and more managers of enterprises do not want to spend money on expensive equipment when organizing VoIP telephony. Many use a SIP adapter, which is a device that costs less than a gateway and does not require a complex installation.
Such equipment operates using the SIP Internet protocol, thanks to which it becomes possible to maintain voice quality when transmitting packages over long distances. SIP-calls are charged much cheaper than when you are using standard telephony.
There are several types of SIP adapters:
- Standard;
- SIP USB adapter;
- ATA adapter;
- FXS adapter.

Usually, a dedicated Internet channel is connected to one jack, to the other - a telephone, to the third - a network card of the computer.
VoIP communication is provided by combining several options to have SIP adapters connected. For some models - for example, SPA2102, there is also an Ethernet port, an integrated router. With it, you can connect to an ISP through a standard connection.
This is an excellent solution for connecting to a PBX and organizing VoIP telephony. Through the functions of call hold, forwarding, video conferencing, you can increase the efficiency of communications. The SIP-adapter paired with a SIP-phone provides even the most remote offices and branches of companies high-quality communication.
However, the installation of the adapter is suitable for telephony with small loads, and with the expansion of the office, you need to buy adapters with a capacity of up to 10 channels, which is not convenient. The greatest number of SIP-adapter ports is 10. It is optimal for the office to use an 8-channel device. Up to 24 analog phones can be connected to the sip adapter with time.
