Alerting a calling party in a Voice over IP (VoIP) setting that a called party might not be able to hear ring-tones. In response to a call arriving on an IP connection, the audible level of ring-tones that are generated by a microphone associated with a VoIP computer application is sampled, and responsive to the audible level of ring-tones being below a minimum threshold, a message is transmitting to the calling party via any available connection that the called party might be unable to hear the ring-tones. |
