VoIP Requirements (Supplementary)

2.3
VoIP Considerations
The Innovaphone VoIP gateway version 10 (or later) is required for teleCARE IP with
speech, as the interface to the PBX.
An interoperability test between the VoIP gateway and main PBX must be performed.
The connection between the PBX and the Innovaphone can be PRI or SIP Trunk
teleCARE IP only supports CODEC G.711 (a-law)
SIP trunk to the VoIP gateway must be set to "Early offer"
teleCARE VoIP shall use the Emergency Call System LAN only.
Ascom Recommendations:
Delay - less than 50 ms is good
Jitter - less than 30 ms is good
Packet Loss - 1% is good (up to 4% is acceptable)
The maximum capacity of the network used for voice should not exceed 25% of the
total network capacity
The maximum capacity of the network used for data and voice together should not
exceed 75% of the total network capacity
