More Information

Problem Details

When performing a firmware version upgrade (e.g. from v7 to v8) in a master/slave installation it is best to do the complete upgrade procedure in one step.

However, in large installations, this is sometimes not possible. In this case a step-by-step migration of each slave PBX is possible. A problem arises when the floating mechanism is used. As a result the slave PBX has no PBX licenses, all PBX licenses are installed on the master PBX and distributed to the slave PBXes when needed. Now you must decide whether you start with upgrading the master PBX or a slave PBX. Either way you will run into problems:

  • update the master PBX first

If the master PBX is updated, you will need to update also the v7 licenses to the new version. Otherwise the master PBX has no licenses and cannot accept the incoming registrations of the slave PBXes or IP-phones. If the license is updated to the new firmware version, the slave PBX running the old firmware will not be able to make use of it - i.e. accept registrations.

  • update a slave PBX first

In this case the slave PBX will receive licenses designed for the previous firmware type (e.g. a v8 slave PBX receives v7 Registration licenses). The slave PBX will not be able to make use of the license - i.e. accept registrations.

Resolution

The master PBX must distribute licenses of both firmware types. To do this, follow this steps:

  1. upgrade the master PBX to the new firmware version (e.g. v8).
  2. use my.innovaphone to download a encrypted version of the old license - type (e.g. v7)
  3. use my.innovaphone to download a encrypted version of the new license - type (e.g. v8). This requires that the license assigned to the device is under SSA.
  4. upload both license files to the master PBX. The master PBX will now distribute both old- and new-type licenses using the floating model.

Known Problems

This method allows the registration of more users then specified by the installed license. The reseller must ensure that in this operation mode is not abused. The maximum amount of registered user is specified by the latest PBX license-type.
