The SRD is a logical representation of your entire VoIP network. The
SRD is in effect, the foundation of your configuration to which all other
previously mentioned configuration entities are associated.
Typically, only a single SRD is required and this is the recommended
configuration topology. As the device provides a default SRD, in a single
SRD topology, the device automatically assigns the SRD to newly created
configuration entities. Thus, in such scenarios, there is no need to get
involved with SRD configuration.
Multiple SRDs are required only for multi-tenant deployments.
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.
