Setting Up IP Extensions
IP extensions communicate with the AltiServ system using IP-based
protocols to carry voice and signaling data. Instead of PSTN, they use a
data networking connection such as an Ethernet 10-Base-T (RJ-45). In
AltiWare OE Release 4.5, AltiServ supports only those devices that are
based on H.323 protocol.
From the end-user's perspective, an IP extension works exactly the same as
an analog extension with the added advantage of being able to work
remotely and without any cabling requirements. There is also no functional
difference in AltiWare features and client applications such as real-time
monitoring, AltiView, and AltiConsole, with the following exceptions
which are unavailable on an IP extension — #81 Hands free–Intercom
mode, #82 (Hands free–Manual answer mode), Distinctive ringing (double
ring for internal calls, single rings for external calls).
In addition, the Location column in the Extension View in AltiAdmin will
show the IP address used by any extension currently logged onto an IP
extension.
IP Connections and Voice Quality
Voice quality can degrade when multiple IP connections use DSL; the
exact numbers will depend on your bandwidth and the number of IP
connections active at one time. If you encounter this problem, you may
need to reduce the number of IP extensions.
