SIP Exchange

IP PBX SIP exchanges support only VoIP lines. Do not operate on the PSTN.

SIP exchanges are offered in 2 versions

1) SIP M/Mx exchanges with smaller configuration parameters, supporting up to 8 VoIP lines:
- version M - without recording the contents of telephone conversations
- version Mx - recording the content of telephone conversations

2) SIP Sx exchanges with higher performance configuration with recording of telephone calls, supporting up to 20 VoIP lines.

SIP exchanges have the same set of functionality as their equivalents IP PBX M/Mx and Sx. They also do not differ generally from them in terms of the external.
