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.
The IP Profile is an optional configuration entity that defines a wide
range of call settings for a specific SIP entity (IP Group). The IP
Profile includes signaling and media related settings, for example,
jitter buffer, silence suppression, voice coders, fax signaling
method, SIP header support (local termination if not supported),
and media security method. The IP Profile is in effect, the
interoperability "machine" of the device, enabling communication
with SIP endpoints supporting different call "languages".
The IP Profile is associated with the SIP entity, by assigning the IP
Profile to the IP Group of the SIP entity.
The Tel Profile is an optional configuration entity that defines a wide
range of call settings for a specific PSTN-based endpoint. The IP
Profile includes settings such as message waiting indication
(MWI), input gain, voice volume and fax signaling method.
The Tel Profile is associated with the PSTN-based endpoint, by
assigning it to the Trunk Group belonging to the endpoint.
Tel-to-IP routing rules are used to route calls from PSTN-based
endpoints to an IP destination (SIP entity). The PSTN side can be
denoted by a specific Trunk Group, or calling or called telephone
number prefix and suffix. The SIP entity can be denoted by an IP
Group or other IP destinations such as IP address, FQDN, E.164
Telephone Number Mapping (ENUM service), and Lightweight
Directory Access Protocol (LDAP).
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 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.
