• Using dynamic IP addressing, the IP extension can log in from any
IP address. However, the IP extensions must always log in via the IVR
and log into voice mail to activate the IP extension. Users who travel
may well prefer dynamic addressing.
Note: AltiGen IP Phone extension users should not activate their IP
Phone by logging into voicemail — instead, #27 should be
used to log in.
Important: When you enable dynamic IP addressing, a physical extension
on one AltiContact Manager system can effectively disable the
IVR 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 IVR. From the dial tone, callers can dial
extension numbers on the second system.
• Using static IP addressing, the extension user logs in from the station
having the IP address. An advantage for virtual extensions is that the
user doesn't have to log in at all; when the user connects to the system,
the extension is immediately recognized as an IP extension. When
physical extensions connect, on the other hand, the system prompts the
user to log in. Static addressing is more convenient for users and may
be preferred by users who work primarily at a specific location.
Important: If you enter the server's IP address as the Logon, IP trunk calls
from another AltiContact Manager system will receive a dial
tone rather than the IVR. From the dial tone, callers can dial
extension numbers on this 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 AltiContact Manager-to-AltiContact Manager connections
using the VoIP Codec Configuration window.
To set up the VoIP codec and configure IP extensions, refer to the VoIP
Codec Configuration section on page 9-5.
