IP-PBX telephone exchanges


We cooperate with Elektronix - manufacturer of ELNIX telephone exchanges. ELNIX exchanges are the most modern and the next generation from analog and digital telephone exchanges.

The combination of traditional telephony and Internet telephony in one device.

Through the built in 8 or 20 channel VoIP gateway, which supports SIP 2.0 and use up to 8 (for version M / Mx) or 20 (for version Sx), Internet phone numbers of one or various internet providers (including traditional operators such as TP SA). Both the traditional PSTN lines and Internet lines SIP (VoIP) are treated equally - all the exchange functions are carried out on both types of lines.

For companies with branch structure (eg, in different cities) Internet technology allows the use of several ELNIX IP-PBX exchanges combined into telephone network, with a uniform internal subscriber numbers for the entire company. Exchanges are plugged into the computer network for example HUB or Switch.
