System Description
teleCARE IP
2.4 VoIP Requirements
Note: See document TD92636GB (IP Infrastructure Requirements) for complete Ascom
network requirements:
2.5 teleCARE IP Compatible Ascom Handsets
Note: Always use the latest available software versions for the handsets.
2.6 Startup Availability Timing
After connecting the teleCARE IP system to the general power supply, the teleCARE IP system needs a
certain time to become fully functional.
VoIP Considerations
An Innovaphone VoIP Gateway is required for teleCARE IP with speech, as the
interface to the PBX.
An inter-operability test between the VoIP Gateway and the main PBX must be
performed
The VoIP Gateway should have the same QoS and VLAN settings as the IP DECT or the
VoWiFi system.
The connection between the PBX and the Innovaphone can be BRI or SIP Trunk
teleCARE IP only supports CODEC G.711 (a-law)
SIP trunk to the VoIP Gateway must be set to “Early offer”
Wherever possible firewalls within the LAN should be avoided
A backbone of at least 100Mb/s is recommended
To ensure the required End-to-End Quality of Service the complete Ascom
environment, including all teleCARE IP room controllers and the NISM, should be
isolated from all other traffic in a separate VLAN.
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 used for data and voice together
should not exceed 75% of the total network capacity
Ascom Testimonials:
Delay - less than 50 ms is good
Jitter - less than 30 ms is good
Packet Loss - 1% is good (up to 4% is acceptable)
