Timing information
The WLAN IP Telephony Manager 2245 sends payload packets to the
handset every 30 ms in a 5 ms window. The handsets are likely to
experience issues if the jitter between the WLAN IP Telephony Manager
2245 and the AP is greater than 5 ms. Ideally, jitter in this part of the
network is 1 ms or less.
