Release 2.1 - An Overview of Features

F-1552 Multiple IP Networks Supported for SIP

Brief Description:

The Multiple IP Networks supported for SIP feature supports creating a SIP stack that can support multiple IP addresses. Each IP Address configured can communicate with a separate SIP Gateway. Once the External Gateway/SIP Signaling association has been configured, the Packet Facility can then be configured to communicate RTP with the specific remote gateway. With this functionality, multiple SIP networks can be serviced using just one SIP stack. This functionality also gives the IMG 2020 the ability to segregate the RTP/Media traffic between different SIP Signaling IP addresses allowing the IMG 2020 to service multiple SIP networks using one SIP stack. In addition to adding the multiple IP address functionality, a Single IP address can also be configured to a SIP stack to allow for backward compatibility to older configurations. This feature is supported in SIP Signaling only. The H.323 stack still supports only one IP address per stack. Refer to the topics in the Related Topics links below for more information.

F-5545 Propagate From Header between SIP calls

Brief Description:

Feature F-5545 Propagate From Header between SIP calls is utilized when the IMG 2020 is within a Trusted Domain and the SIP Privacy functionality is enabled. When receiving an INVITE message, the From Header is received along with the P-Asserted and/or Remote Party ID Header. These Headers are propagated to the outgoing leg with the username of either the P-Asserted and/or Remote Party ID Header. Feature F-5545 changes that behavior. When F-5545 is set to enabled, the Username parameter in the From Header on the incoming will be propagated to the From Header on the outgoing side. In this scenario the From Header is the same on the incoming and outgoing side.

F-6202 SRTP

Brief Description:

SIP SRTP on the IMG 2020 supports RFC 3711 (The IP media layer security standard) and RFC 4568 (The IP signaling security standard). The IMG 2020 provides security, confidentiality, message authentication, and replay protection for both RTP and RTCP packets. This is achieved using a cryptographic key and other parameters that serve to configure security. To utilize SRTP over SIP, the IMG 2020 must first have the SIP Signaling over TLS Overview functionality configured. SIP Signaling over TLS was introduced to make the IP signaling layer secure. SRTP and SRTCP are added to make the voice and data secure over the RTP stream. Refer to the topics in the links of the Related Topics section below for more information on this feature.

F-6259 Dynamic Channel Density Management

Brief Description:

The Dynamic Channel Density Management Mode in the Physical Node object was designed to make use of the most possible IP media channels that are available on the IMG 2020 when utilizing multiple codecs. The IMG 2020 utilizes codecs such as AMR-WB which are very labor intensive and use up more DSP resources than other generic g.711 codecs. When codecs such as AMR-WB are utilized, the number of channels available drops. With Media modes such as LBR or Audio 3G, there are a set number of channels available that are statically configured at bootup. The Dynamic Channel Density Management feature does not statically set up the number of channels available but rather uses a Resource Point Pool. Each call with its configured codec uses a set number of resource points from the pool. The resource points are removed and replaced as calls are made and the number of resources depends on the number of DSP's available in the system. This scenario allocates channels dynamically so the maximum number of channels are used depending on the codecs being employed at any point in time. To aid the customer with the number of DSP's needed for each blend of codecs, a Media Mode Assignment Calculator has been created. With this calculator, different parameters such as the number of DSP's installed, the percentage of each codec that will be used, and if SRTP is used, can be configured. These parameters determine what percentage of the available codecs will be used. Once all parameters are entered, a total channel count available will be calculated as well as the channel count available for each individual codec. For more information on utilizing Dynamic Channel DensityCalculator, contact your nearest Dialogic Sales and Support Team Personnel at Contact Information | Regional Offices | Dialogic and they can assist with any questions related to the Calculator.

F-6297 Message and Header Size Restrictions

Brief Description:

Feature F-6297 Message and Header Size Restrictions limits the overall size of any incoming SIP Messages, and limits the number of specific headers that can be contained in a single incoming SIP message. Limiting the SIP messaging reduces the SIP processing required for large messages which limits the complexity of SIP Processing and protects the SIP components from malformed or malicious messages. The Message and Header Size Restrictions feature is configured in the SIP Signaling object of the Web GUI. Refer to the links in the Related Topics section below for more information on this feature.
