AspireNet Incoming Trunk Access Route
Easy Edit – Advanced Items/VoIP/Networking/AspireNet CVM/AspireNet Remote Trunk Access/AspireNet
Incoming Trunk Access Route (PRG21-16)
This controls which local Trunk Route an incoming AspireNet call has access to for outgoing trunk calls.
Set the Trunk Route on a per AspireNet Networking System ID.
AspireNet Busy Lamp Information
Easy Edit – Advanced Items/VoIP/Networking/AspireNet CVM/AspireNet Busy Lamp Information (PRG20-
01-04)
This is a timer that controls the frequency of Busy Lamp updates between AspireNet nodes. Enter a value
(in 100ms increments) of how often the local system should send out BLF updates to all other systems in
the network. 1 = 100ms, 5 = 500ms etc.
AspireNet Park Hold Operation
Easy Edit – Advanced Items/VoIP/Networking/AspireNet CVM/AspireNet Park Hold Operation (PRG24-03)
Park Hold information is shared between all nodes in an AspireNet network so any user can pick up a
Parked call from any system. In some circumstances this operation may be undesirable and each system
may wish to see only its own Parked calls. To do this put all extensions from each system into its own Park
Hold Group. E.g. put all extensions on System ID 1 into Park Group 1 and all extensions on System ID 2
into Park Group 2 etc.
Centralised Voicemail
Easy Edit – Advanced Items/VoIP/Networking/AspireNet CVM/Centralised Voicemail (PRG45-XX)
AspireNet will support the use of a single voicemail system for the entire network. A user may call into the
voicemail from anywhere in the network and perform most functions as if the voicemail were located on
their premises.
Please see the Centralised Voicemail page for further details.
AspireNet Codec
Easy Edit – Advanced Items/VoIP/Networking/AspireNet CVM/AspireNet Setup/AspireNet CODEC Settings
AspireNet can use various CODECs. A CODEC is a standard for converting an analogue signal to digital.
This conversion process is handled by the DSP (Digital Signal Processors) on the GPZ-IPLE card.
Each CODEC has different voice quality and compression properties. The correct choice of CODEC will be
based on the amount of bandwidth available, the amount of calls required and the voice quality required.
Available Codec's for AspireNet
· G.711 64Kbps codec MOS 4.4
· G.722 64Kbps codec MOS 4.4
· G.729 8Kbps codec MOS 4.0
The bandwidth values quoted for these codec's are for the digitized speech in one direction only. The
actual bandwidth required for a call will depend on many other factors and will be much higher than these
figures.
The above MOS values are quoted for ideal network conditions. The value could be lower depending upon
the network performance.
To change the codec in use in an AspireNet network use the Audio Capability Priority setting in Easy Edit
