One of the characteristics of the BRAVE protocol, and which is common to all the equipment of the Quantum and Ikusnet families, is the use of Call Profiles.
Call Profiles are temporary configurations that affect both the calling and the called equipment. They allow, in the first place, to size the reception buffer of the remote device. This reception buffer is what allows IP packets, which do not arrive at their destination in a perfectly synchronous manner, to be received in sufficient time to be able to reconstruct the original audio. The dimension of this buffer is the one that will mark the delay of the transmission. By default, Quantum equipment includes three different call profiles: Low Delay (100ms), Mid Delay (300ms) and High Delay (500ms). These profiles can be edited within the Streaming menu and adapted to the values required by the user.
In addition to configuring the delay of the remote equipment, it is possible to configure the compression algorithm to be used in the call (OPUS or APT-x) and the transmission mode (Bonding or Diversity)
Call profiles change the codec settings ONLY DURING THE CALL. When the communication ends, the two devices return to the settings before the start of the call. To make permanent settings you must use the Presets.
