Chapter 2 SIP Protocol Subscriber Features

Cisco BTS 10200 Softswitch-Based Features

Call Forwarding Activation and Deactivation

Activation and deactivation of call forwarding features uses the star code. Alternately, the feature may be activated or deactivated by using the Services key on certain phones.

With SIP support, the call forwarded to number can be a Centrex extension number (only applicable for business users) or an E.164 number.

Note Forwarding to a URL (AOR) is not supported in Release 4.4.

SIP subscribers do not hear a final dial tone upon completing activation or deactivation. Instead, an announcement plays for the subscriber, indicating that the status of the forwarding feature is being activated or deactivated. This is irrespective of the Final Stage Dial Tone (FDT) flag (Y/N) provisioned for these features.

Call Forwarding to an E.164 Number or an Extension Number

In Release 4.4, activation is accomplished using single-stage dialing. This applies to all activation and deactivation.

Calling Name and Number Delivery

Calling number delivery (CND) provides the SIP subscriber endpoint with the date, time, and calling number in an incoming call. When the called subscriber line is on hook, the calling party information is delivered during the long silent interval of the first ringing cycle. Telcordia document GR-30-CORE specifies the generic requirements for transmitting asynchronous voice band data to the SIP subscriber line.

Rules

The rules associated with populating the calling party number in the outgoing INVITE from the Cisco BTS 10200 to the terminating SIP phone are as follows:

•If the calling number is available, and the presentation indication is not restricted, the number is populated into the user information portion of the From: header. Otherwise, this user information field is empty.

•If the calling number is available, and the presentation indication is restricted, the display name field of the From:header is set as ‘Anonymous.’ Otherwise, the following logic is used to populate the name display field of the From: header:

–If the calling name exists and the calling name presentation indication is not restricted, then the calling name is populated into the display name field of the From: header. Otherwise, the display name field in the From: header is left empty.

Calling Number Delivery Blocking (CNDB) controls whether the caller’s DN is delivered to the called party. CNDB is supported on a call-by-call basis, by dialing a privacy feature code or by using the feature key to prevent the subscriber’s DN from being delivered on the next call.

BTS 10200 specifications

Cisco Systems BTS 10200 is a robust platform designed to meet the demands of modern telecommunications. This session border controller (SBC) facilitates the management of voice over IP (VoIP) traffic, enabling secure and efficient communication across diverse networks. The BTS 10200 plays a critical role in integrating voice and data services while ensuring high-quality user experiences and regulatory compliance.

One of the standout features of the BTS 10200 is its ability to support a wide range of protocols, making it highly versatile. It is compatible with both legacy systems and modern IP-based solutions, ensuring seamless interoperability. This adaptability allows service providers to migrate to next-generation networks without disrupting existing services.

The BTS 10200 is built upon a highly scalable architecture, allowing it to handle large volumes of traffic. This scalability is crucial for service providers as they expand their networks to accommodate more users and services. The platform supports hundreds of thousands of simultaneous sessions, which is essential for large-scale deployments such as in mobile and fixed-line networks.

Security is a paramount feature of the BTS 10200. It incorporates multiple layers of security protocols, including encryption and authentication mechanisms, to protect against unauthorized access and potential cyber threats. The platform also features robust filtering and Denial of Service (DoS) protection, ensuring that VoIP services remain stable and reliable even under adverse conditions.

Quality of Service (QoS) management is another critical characteristic of the BTS 10200. It allows for traffic prioritization to ensure that voice signals maintain clarity and reduce latency. Through advanced traffic shaping and management techniques, service providers can enhance the overall user experience even during peak usage periods.

Furthermore, the BTS 10200 supports a wide array of management and monitoring tools, enabling network administrators to gain insights into performance metrics, traffic trends, and system health. This data-driven approach allows for intelligent decision-making and proactive maintenance.

In summary, the Cisco Systems BTS 10200 is a powerful, secure, and scalable solution for managing voice and data services in today's complex telecommunications environment. Its combination of protocol support, robust security measures, QoS capabilities, and management tools positions it as a key asset for service providers looking to enhance their offerings and ensure reliable communications for their users.
