Configuration
Important: If you enter the server’s IP address as the Logon, IP trunk calls
from another AltiServ system will receive a dial tone rather
than the Auto Attendant. From the dial tone, callers can dial
extension numbers on this system.
• Using dynamic IP addressing, the IP extension can log in from any
IP address. However, the IP extensions must always log in via the Auto
Attendant and log into voice mail to activate the IP extension. Users
who travel may well prefer dynamic addressing.
Important: When you enable dynamic IP addressing, a physical extension
on one AltiServ system can effectively disable the Auto
Attendant for system-to-system IP calls to the second system.
This happens if a physical extension on one system calls a
second system via an IP trunk, logs into an extension, and
enables an IP connection. As long as the connection is active,
all IP trunk calls from the first to the second system will receive
a dial tone rather than the Auto Attendant. From the dial tone,
callers can dial extension numbers on the second system.
Setting VoIP Codecs
The default codec for static IP extensions is G.711, which gives a
bandwidth of approximately 64 kbps. This is appropriate for lease lines or
high-speed connections. The default codec for dynamic IP extensions is
G.723, which gives a bandwidth of approximately 6.4 kbps. This is
appropriate for internet connections.
You can change these defaults and set dynamic IP addressing ranges and
codecs for AltiServ-to-AltiServ connections using the VoIP Codec
Configuration window.
To open the VoIP Codec Configuration window:
• Choose VoIP Codec Configuration from the Management menu.
