How to mute PJSUA call in android

I am developing VOIP app in android using PJSUA, here I want to mute call

I am reading doc related to PJSUA and I find method that is used for such purpose but could not implement in android APP, please anyone who can help me to set call in mute mode

Here I provide the detail from PJSUA docs,

pj_status_t pjsua_conf_adjust_rx_level (pjsua_conf_port_id slot,
float level )

Adjust the signal level to be received from the specified port (to the bridge) by making it louder or quieter.


  • slot: The conference bridge slot number.

  • level: Signal level adjustment. Value 1.0 means no level adjustment, while value 0 means to mute the port.


  • PJ_SUCCESS on success, or the appropriate error code.

I want solution like that to hold call in android using PJSUA

public void holdCall() {
CallOpParam prm = new CallOpParam(true);
try {
} catch (Exception e) {
