• CHANGE IT: SET-CSBACKUPSERVICECONFIGURATION –SYNCINTERVAL 00:05:00
POOL PAIRING – WHAT DOES IT LOOK LIKE
• DURING POOL OUTAGE• BUDDY LIST IS NOT AVAILABLE
• CONFERENCING IS NOT AVAILABLE
• CHANGING CALL FORWARDING RULES NOT AVAILABLE

LYNC 2013 BANDWIDTH NEEDS
• POTENTIAL FOR SIGNIFICANTLY MORE BANDWIDTH USAGE• NEED TO MAKE SURE TO ACCOUNT FOR BANDWIDTH
• RTVIDEO TO H.264 SVC
• CLIENT CAN STREAM UP TO AND RECEIVE UP TO FIVE VIDEO STREAMS
• AUDIO DIDN’T CHANGE
• RTAUDIO / MAX 62 KBPS & G722 / 101 KBPS
