Configure AVAudioSession singleton for playback and record

Implement 2 GKVoiceChatClient protocol methods

- (NSString*) participantID

- (void) voiceChatService:(GKVoiceChatService*)voiceChatService sendData:(NSData*)data toParticipantID:(NSString*)participantID

Implement GKSession data receive handler

- (void) receiveData:(NSData*)data fromPeer:(NSString*)peer inSession: (GKSession*)session context:(void*)context

Set GKVoiceChatService system singleton client

[[GKVoiceChatService defaultVoiceChatService] setClient:clientObject];

Initiate voice chat session

[[GKVoiceChatService defaultVoiceChatService] startVoiceChatWithParticipantID:otherPeerID error:nil];
