Conference Bridge (2.10) - PJSIP
https://www.pjsip.org/pjmedia/docs/html/group__PJMEDIA__CONF.htm
Enable unidirectional audio from the specified source slot to the specified sink slot. Application may adjust the level to make signal transmitted from the source slot to the sink slot either louder or more quiet. The level adjustment is calculated with this formula: output = input * (adj_level+128) / 128. Using this, zero indicates no ...

p_conf. ) Create conference bridge with the specified parameters. The sampling rate, samples per frame, and bits per sample will be used for the internal operation of the bridge (e.g. when mixing audio frames). However, ports with different configuration may be connected to the bridge. In this case, the bridge is able to perform sampling rate ...

Audio stutter is observed when configuring pjsua to use audio switchboard instead of the default conference bridge, and when narrowband clock rate is used by the media (for example, play file). To reproduce: enable switchboard, by declaring this in config_site.h: #define PJMEDIA_CONF_USE_SWITCH_BOARD 1 run pjsua to stream file
