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 100-Base-T (RJ-45).
AltiServ supports only those devices that are based on H.323 protocol.
From the end-user's perspective, an IP extension using an AltiGen IP phone
works exactly the same as an analog extension with the added advantage of
being able to work remotely and without any cabling requirements.
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.
AltiGen IP Phone Service
AltiGen IP Phone Service runs on the same system as AltiAdmin, is
installed together with AltiAdmin, and connects to AltiAdmin through
enhanced A protocol on behalf of AltiGen IP Phones.
Intercom with IP Phones
Intercom (#93) is supported on the Triton Analog extension with
Al phones. Intercom is supported on IP extensions as well,
provided AltiGen IP Phones are used. An extension user can use the feature
code #93 to intercom an IP extension associated with an AltiGen IP Phone.
If this phone is in idle state, an H.323 session will be established, the phone
speaker will be turned on automatically, a short ring tone is generated, the
Speaker is turned on, and the voice path is connected. If the IP phone is
busy, the caller will follow the call busy handling of the AltIGen IP Phones’
configuration.
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.
