DETECT PHONE CALL STATUS AND AUTO MUTE/UNMUTE/RECONNECT VOIP SESSION FOR SMARTPHONES

ABSTRACT

    Techniques are presented herein to detect phone call status (phone is ringing, the call is rejected, the call is accepted/on the phone, the phone call has ended, etc.) in a VoIP session. When the phone is ringing, the audio/VoIP is muted and other attendees in a meeting are notified. When the call is accepted, other attendees are notified that the user is on the phone. When the call has ended, the audio is unmuted or reconnected the VoIP session.

DETAILED DESCRIPTION

    Nowadays, more and more people use Smartphones (iPhone, Android, BlackBerry, Windows Phone, etc.) to join online conferences/meetings (e.g., Cisco WebEx Meetings, Microsoft Lync, Citrix GoToMeeting, etc.) or group audio/video chat (Cisco Jabber, Skype,Tecent WeChat/QQ, etc.).

    When a user in an online conference or a group audio/video chat is on Smartphone, he/she may receive a call, in one of the following scenarios.

    Case 1. The phone call and VoIP session are not compatible in one Smartphone, such as an iPhone┬« phone. When the phone is ringing (receiving a call) or accept a call (on the phone), the VoIP call will be disconnected automatically by the phone. In this case, the conference or group audio/video chat may be interrupted because the user's audio is disconnected, and other attendees cannot talk with the user and the user
cannot hear what other attendees are saying. In order to solve this problem, a mechanism is proposed to notify other attendees that the user is receiving a call or on the phone. When the call has ended, the user can be automatically reconnect to the audio session and notify other attendees the user's audio is reconnected.

    Case 2. The phone call and VoIP session are compatible in one Smartphone, such as HTC C620e (WP8). When the phone is ringing (receiving a call), the noise of the ringing may disturb other attendees (other attendees can hear the ringing). In order to solve this problem, a method is proposed to automatically mute the audio when the user is receiving a call and notify other attendees the user is receiving a call. When the user rejects the call, the audio is automatically unmuted and the other attendees are notified.

    When the user accepts the call, although the VoIP call is still connected, the input/output of the VoIP call is silenced automatically in most Smartphones. In this case, other attendees also cannot talk with the user and the user cannot hear what other attendees say. In o...
