The Broadworks platform uses an enhanced algorithm called Overload Control to offer protection when a cluster node is under severe conditions. The goal is that during an overload period of 150% the throughput will be no less than 90%.

Acme Packet SIP Header Manipulation Rules
Posted: 23rd April 2010 by Mark in Acme Packet, BroadWorks, SIPThis is an example of how to modify a SIP header with an Acme Packet Session Border Controller (SBC). An SBC is a device most commonly used by Service Providers to provide topology hiding between their SIP platform and the public Internet.

As of this writing the latest version of the Unix application sudo is not compatible with Broadworks. Version 1.6 and below will work appropriately although Broadsoft is working to fix this. In the event 1.7 is inadvertently installed and Broadworks will not start then the sudo application must be downgraded. Broadsoft has provided an advisory [...]
As the database grows on the Broadworks Application and Network servers there will be a need to change the memory allocation for the TimesTen datastore. The Maintenance Guide does not contain all the required steps. The rule of thumb is the allocated “perm” size should not exceed more than 25% of total system memory and [...]

This is fairly common [...]

Unscreened Calls is common with TDM PRI customers who want to send a From DN that does not reside in their Trunk Group. With SIP trunks [...]
A very quick note regarding an upgrade from Broadworks R14.SP8 to SP9. Broadworks appears to contain a bug when using the Generic SIP Smart Proxy device in SP9. I am saying “appears” because at the time I am writing this post Broadsoft TAC has not officially acknowledged this as a bug. The behavior did not [...]
Recently I upgraded Broadworks R14.SP8 to SP9. I activated Enterprise Trunking which provides the ability to use Unscreened Calls for Trunking customers if you turn it on in a Trunk Group Profile. The purpose of Unscreened Calls is to allow a customer PBX to send a calling line ID which may contain a From number [...]
