Problem Description

Once the patch AP.as.22.0.1123.ap374528 is applied, all the SIP SUBSCRIBE for line-seize subscriptions fail as the Application Server (AS) sends a SIP NOTIFY with Subscription-State equal to "terminated".

Background

Note: This field notice was originally posted in the BroadSoft Xchange portal and has been moved over to Cisco.com as-is for historical purposes.

Problem Symptom

All devices that require line-seize to establish a call will get fast-busy and the originating call will not be possible.

Workaround/Solution

BroadWorks patches can now be downloaded through the Cisco Software Download Center after logging in with your Cisco.com (CCO) account.

The version of BroadWorks that is currently deployed as well as the patches currently activated can be checked by executing the get versions all command from the CLI. More information on how to check the patch level can be found in the Cisco BroadWorks Maintenance Guide.

Workaround

Remove the AP.as.22.0.1123.ap374528 patch until the new patch is available.

Patch

AP.as.22.0.1123.ap374820 is now available on Xchange to address this issue.
