Dialogic® BorderNet™ 4000 SBC Product Description Document

• Performing SIP message and header tests and manipulations, such as: BeginsWith,

Contains, EndsWith, Equal, MatchPattern, NotEqual, RemoveString, ReplaceString,

and so forth.

PRACK

SIP returns two types of responses: a provisional response or a final response.

• A final response (2xx – 6xx) reliably conveys the request processing result.

• A provisional response (1xx) does not acknowledge the request and is not reliable.

When a provisional SIP response (1xx) must be delivered reliably, a Provisional Response

Acknowledgement (PRACK) message is added to the provisional response. The BorderNet

4000 SBC supports PRACK and asymmetric PRACK to ensure reliable transmission of the

provisional response.

Call Routing

The BorderNet 4000 SBC provides an extensive array of on-board (built-in) and external call

routing capabilities. The on-board routing functions include:

• Message-based routing

• Static Routing

• Policy-based routing

• Time-based routing

• Number normalization and prefix/suffix support

• Least Cost Routing

• ASR and Quality based routing

• Multi-Tenant Routing

Note: LCR, ASR, route quality, and multi-tenant routing requires a separate Dialogic

partner product for generation of the appropriate routing table

Local DNS

The BorderNet 4000 SBC uses a local DNS table to support FQDN-to-FQDN or FQDN-to-IPv4

address and port number resolution.

Core Network Load Balancing—Incoming Sessions

Load balancing distributes the traffic across multiple remote endpoints. The BorderNet 4000

SBC supports load balancing for inbound sessions to the core network as follows:

• The Fully Qualified Domain Name (FQDN) can be assigned multiple IP addresses

within a single subnet, with a maximum of 24 IP addresses per FQDN.

• Priorities and weights can be configured for the group of IP addresses associated

with the FQDN.
