This article contains a list of abbreviations and acronyms used in relation to Zenitel products.
- ACDP (AlphaCom Data Protocol) - A proprietary protocol used for communication between ICX-AlphaCom (or AlphaCom) servers, as well as for integration to 3rd party systems.
- AGC (Automatic Gain Control) - Brings the microphone signal to an appropriate level when speaking with a low voice or at a distance.
- AEC (Acoustic Echo Cancellation) - AEC is needed when a far end signal (voice originating at the other end of the communication) is played over a loudspeaker into a reverberant acoustic space and is picked up by a microphone. If the AEC algorithm were not implemented, an echo corresponding to the delay for the sound to travel from the speaker to the microphone, as well as any reverberation, would be returned to the far end. In addition to sounding unnatural and being unpleasant to listen to, the artifacts substantially reduce speech intelligibility.

SIPS is SIP, extended with TLS (Transport Layer Security). With this TLS, a secure connection between IP PBX and VoIP telephone can be established using a handshake approach.
- SNMP (Simple Network Management Protocol) - is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.

- SRTP (Secure Real-time Transport Protocol) - To overcome the security flaws of SIP and RTP and safely make secure calls via the internet, encrypted versions of both protocols have been developed. SRTP encodes the voice into encrypted IP packages and transport those via the internet from the transmitter (IP phone system) to the receiver (IP phone or softphone), once SIPS has initiated a secure connection. To allow the receiver to decrypt the packages, a key is sent via SIPS, while the connection is initiated in the previous step.
- SSL (Secure Sockets Layer) - is standard technology for securing an internet connection by encrypting data sent between a website and a browser (or between two servers). It prevents hackers from seeing or stealing any information transferred, including personal or financial data.
