New Features

The S-Cz8.3.0m1 release supports the following new features and enhancements.

Note:

System session capacity and performance are subject to variations between various use cases and major software releases.

SIP Header Automation for Microsoft Teams

The E-SBC can manipulate SIP message headers in the format required by Microsoft Teams, rather than with custom Header Manipulation Rules. The following parameters are used for this function:

session-agent, ping-response
realm-config, teams-fqdn-uri
realm-config, sdp-active-only

See the Configuring the Oracle ESBC to Microsoft Teams Direct Routing Media Bypass - Enterprise Model Document for details.

SIP to SIP-I Interworking Enhancement

Oracle plans to enhance SIP to SIP-I interworking over the course of several releases. For the S-Cz8.3.0m1 release, this interworking now supports populating of IAM parameters based on SIP INV, support for REL/RLC messages, reason code mapping from 4xx, 5xx, 6xx final responses into REL and vice versa, support for supplementary services, and support for parsing of SPIROU.

See "SIP ISUP Interworking" in the ACLI Configuration Guide.

Registration Event Subscription Counters

This release provides new counters for registration event subscriptions.

See "SIP Registration Event Package Support" in the ACLI Configuration Guide.

HA Deployments over Oracle Cloud Infrastructure

This release supports HA deployments over Oracle Cloud Infrastructure (OCI).

See the Platform Preparation and Installation Guide.

MSRP Statistics

This release provides MSRP byte and packet counters at the end of each MSRP call.

See "MSRP Statistics" in the ACLI Configuration Guide.

IMS-AKA Subscriber Support

The OCSBC supports up to 400,000 IMS-AKA subscribers, but is dependent on configuration. For example, Oracle recommends at least 2 forwarding cores and 52GB to support 400,000 subscribers. In addition, the OCSBC allocates resources for IMS-AKA based on your setting for the IMS-AKA endpoint entitlement. This means that you must also set the entitlement prior to IMS-AKA operation so that the system correctly allocates resource utilization.

Thresholds to consider when you set the entitlement include:

1 Forwarding core:
- Less that 8GB memory support only 500 IMS-AKA subscribers
- 8GB memory supports 48,000 IMS-AKA subscribers
- 10GB memory supports 80,000 IMS-AKA subscribers
- 16GB memory supports 104,000 IMS-AKA subscribers
2 Forward cores:
- 16GB memory supports 112,000 IMS-AKA subscribers
- 20GB memory supports 144,000 IMS-AKA subscribers
- 24GB memory supports 176,000 IMS-AKA subscribers
- 32GB memory supports 240,000 IMS-AKA subscribers
- 48GB memory supports 368,000 IMS-AKA subscribers
- 52GB memory supports 400,000 IMS-AKA subscribers

See "IMS Support" in the ACLI Configuration Guide.

OCSR Platform Support

The OCSR is supported over the X8-2 platform, beginning with version S-cZ8.3.0m1p2.

See "Oracle Server X8-2 Platform Preparation" in the Platform Preparation and Installation Guide.
