Specications
System
Maximum number of phone lines: 48, when used with aLaw or uLaw codecs for VoIP lines.
(Higher quailty codecs, such as G.722, consume more system resources and result in a de-
creased number of total lines available.)
Maximum number of SIP numbers: 250
Maximum active on-air calls: 30
Number of hybrids: one per each active line
Maximum number of studios: 20
Maxiumum number of Livewire input/output channels - 20 systemwide
