VoIP Considerations
The Innovaphone VoIP gateway version 8 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 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”
teleCARE VoIP shall use the Emergency Call System LAN only.
