Webex Onboarding retry timer changes
Multiplatform Phones (MPP) support Webex services starting with MPP 11.3.6 release. This feature is enabled seamlessly for all the MPP phones registered to Webex Calling (learn more) and also for the Webex for Broadworks service providers that enable it (learn more). In the prior releases, for the cases when MPP device is unable to onboard to Webex services, it would retry every two minutes. We are changing this retry timer to gradually back off to once every 24 hours. If you are trying to resolve the issues with Webex services connection, you can force the MPP phone to retry immediately by rebooting it.
PRT (Problem Report Tool) file name restrictions
This firmware does not allow the use of “.” character in PRT name either used directly or included as a part of the macro variable.
