Discord is an instant messaging and VoIP social platform which allows communication through voice calls, video calls, text messaging, and media.Communication can be private or take place in virtual communities called "servers".
A voice call originating in the VoIP environment also faces least-cost routing (LCR) challenges to reach its destination if the number is routed to a mobile phone number on a traditional mobile carrier. LCR is based on checking the destination of each telephone call as it is made, and then sending the call via the network that will cost the ...
The 3GPP has defined the Voice Call Continuity (VCC) specifications in order to describe how a voice call can be persisted, as a mobile phone moves between circuit switched and packet switched radio domains (3GPP TS 23.206). Many mobile phones are becoming available that support both cellular and other broadband radio technologies.
Single Radio Voice Call Continuity (SRVCC) provides an interim solution for handing over VoLTE (Voice over LTE) to 2G/3G networks. The voice calls on LTE network are meant to be packet switched [1] calls which use IMS system to be made. To make it inter operable with existing networks, these calls are to be handed over to Circuit switched calls ...
Interactive voice response (IVR) is a technology that allows telephone users to interact with a computer-operated telephone system through the use of voice and DTMF tones input with a keypad. In telephony , IVR allows customers to interact with a company's host system via a telephone keypad or by speech recognition, after which services can be ...
Enhanced Voice Services (EVS) is a superwideband speech audio coding standard that was developed for VoLTE and VoNR. It offers up to 20 kHz audio bandwidth and has high robustness to delay jitter and packet losses due to its channel aware coding [ 1 ] and improved packet loss concealment. [ 2 ]
Voice-scrambling systems have been selectively used for this kind of communications circuit since the 1980s, based on operational needs. Since personal computers became cheap and readily available in the 2000s, time compressed voice scrambling for one-way and bi-directional circuits is a practically free technology.
