Latency is the time between the moment a voice packet is transmitted and the moment it reaches its destination. In SIP trunking, it may result from an abrupt variation in signal characteristics, such as when a data packet arrives either ahead or behind a standard clock cycle. Jitter is used to describe a short fluctuation in the transmission of a voice signal. Telecommunications hardware that is designed for use over the internet is commonly called “IP enabled.” IP enabled phones may be referred to as “SIP Phones” or “VoIP Phones.” IVR (Integrated Voice Response)Īn application that provides full-featured integrated voice response capability to answer inbound calls, perform database lookups, re-direct calls automatically, etc. It is the network layer protocol in the TCP/IP communications protocol suite. Internet Protocol is a standard that defines the way that data is transmitted between the source device and the destination. It also ensures that calls to 911 are routed to the nearest Public Safety Answering Point. This service allows customers to set any physical address as the one to be relayed to emergency dispatchers when 911 is dialed. DID (Direct Inward Dialing)Ī method of directly dialing the number of a IP Phone or a telephone attached to a PBX without routing calls through an attendant or an automated attendant console.
#Telecom sip definition software#
Software that integrates voice communications systems with computers for contact center and office automation applications. The highly compressed signals require less internet bandwidth, while less compression is associated with better voice quality. Different codecs have different levels of compression.

CodecĪ codec, which stands for coder-decoder, converts an audio signal (your voice) into compressed digital form for transmission (VoIP) and then back into an uncompressed audio signal for replay. A CDR contains details such as the called and calling parties, originating switch, terminating switch, call length, and time of day. CDR (Call Data Record)Ī stored database record containing data about a specific call. The term is commonly used interchangeably with VoIP, internet telephony or IP telephony.

Broadband Telephonyīroadband telephony refers generally to voice calls that are transmitted over the internet, rather than traditional telephone lines. It is described usually in bits per second (bps) or bytes per second for digital devices and in cycles per second, or Hertz (Hz) for analog devices. Bandwidthīandwidth is the amount of data that can be transmitted over a communication line in a specified period of time. ATAs are used to connect legacy hardware to more modern telecommunications equipment. ATA (Analog Telephone Adaptor)Īn ATA is a hardware device that connects analog (non-IP enabled) telephones, PBX systems, fax machines, door alarms and similar devices to digital systems or an internet-based telephony network. ACD (Automatic Call Distribution)ĪCD is used to deliver calls to contact center agents based on user inputs or pre-defined rules including skills-based routing.

That’s all well and good if you are involved in it every day, otherwise, it can cause a great deal of confusion. In a very similar way, telecommunications has a syntax that is unique to it. Software developers and scientists can sound like they are speaking in tongues.

Doctors and lawyers, for instance, throw out words and phrases that make no sense to anyone else. Many industries or professions eventually evolve a language all their own.
