VoIP Contest: Round 1 General info about the contest is available on @contest.
The task in this round of the VoIP Contest is to build a system for testing voice calls with two participants.
Contest Overview A is a user making a voice call (caller). B is a user receiving a voice call from A (callee). The VoIP Relay is an intermediary server, which takes data from each of the participants and relays it to the other party. The relay has an IP-address, a port, and 2 “tags” per call – to distinguish between different calls and different participant roles in each of the calls (caller/callee). All data exchanged by A and B is encrypted. For the call to work, both parties must use the same encryption key. Depending on the network conditions (Edge, 3G, LTE, Wi-Fi) data packets may be lost or reordered and the sound may get distorted. Your goal is to automate the process of testing sound transmission under various conditions. [ Caller A ] <-> [ VoIP Relay ] <-> [ Callee B ]
