IP telephone set details

Once a Nortel 20XX or 11xx IP telephone registers with the system, this panel displays the

terminal parameters.

The telephone is identified to the system by its IP address, so this cannot be changed. If you need

to change the IP address of a telephone, you need to deregister the telephone and then register it

again with the new IP address.

Figure 37 IP Terminal Details (Telephony Resources) subpanel

Table 31 describes the fields on this panel.

Default jitter buffer None

Auto

Small

Medium

Large

Choose one of these settings to change the default jitter buffer size:

None: Minimal latency, best for short-haul networks with good

bandwidth.

Auto: The system will dynamically adjust the size.

Small: The system will adjust the buffer size, depending on CODEC

type and number of frames per packet to introduce a 60-millisecond

delay.

Medium: 120-millisecond delay

Large: 180-millisecond delay

G.729 payload size

Set the maximum required payload size, per codec, for the IP

telephone calls sent over H.323 trunks.

“Configuring VoIP trunk media parameters” on page 416.

IP phone 2004 Note: Phase 1 sets that were manufactured in

Australia can freeze during a call, and remain frozen until power

cycled. For sites that experience this problem, set the G.711

payload size (ms) value to 20 ms.
