Configuration Terms Description
IP-to-Tel (Trunk Group)
Routing Rules
IP-to-Tel routing rules are used to route incoming IP calls to Trunk
Groups. The specific channel pertaining to the Trunk Group to which the
call is routed can also be configured.
Accounts Accounts are used to register or authenticate PSTN-based endpoints with
a SIP entity (e.g., a registrar or proxy server). The device does this on
behalf of the PSTN-based endpoint. Authentication (SIP 401) is typically
relevant for INVITE messages forwarded by the device to a SIP entity.
Registration is for REGISTER messages, which are initiated by the
device on behalf of the PSTN-based endpoint.
The following figure shows the main configuration entities and their involvement in call
processing. The figure is used only as an example to provide basic understanding of the
configuration terminology. Depending on configuration and network topology, the call
process may include additional stages or a different order of stages.
