Jitter Depth (ms): (Default: 30ms)
The jitter buffer value must be at least 10 ms more than the largest packet size in your
preference selections. For better delay performance, keeping the minimum allowed value
is recommended.
IP Address:
If the IP phone uses static IP assignment, then use this field to specify the IP address for
each telephone.
Use DHCP:
Check this box if the IP phone obtains its address from a DHCP server on the network. In
this case, the IP phone uses its Extension Number to register with the IAD(8)-U() ETU.


The following example assumes that the IP Address 192.168.1.105 is assigned on Port 2
of the IAD(8)-U( ) ETU:
K
K
Extension: (Informational)
The extension ID is provided for informational purposed only. This extension is derived
from settings that have been made in Key System programming MB 4-10.

Outside Firewall:

Enable Peer-to-Peer Connections.
Check this box to improve voice quality and bandwidth performance for calls between IP

Hardware, Installation and Maintenance Manual
The Extension Number assigned in Megaco Terminal programming must match Key
System Programming (MB 4-10). The telephone number will be assigned by the Elite
system according to the related port number.
If DHCP is used, and an extension number is changed on the KTS programming
(MB 4-10), then the IAD(8)-U( ) must be rebooted in order for it to operate properly.
The station number for the IP Telephone (on Port 1) = 108
The station number for the IP Telephone (on Port 2) that has DHCP IP address
192.168.1.105 = 109
If MB 4-10 has not been configured prior to the IAD(8)-U10 ETU initializing, the
extension information will be displayed as "0" and will not become effective until the ETU
has been reinitialized.
This function is only supported for IP terminals over the same subnet. This function is
not supported on IP terminals that are registered over the Internet.
