OCS 2007 R2 Tanjey “push” update

How to force Tanjey (ip softphones) to update? it’s a trick called 'push’ update:

1. upload R1 FW 1.0.522. 101 (1.23)
2. upload R2 FW 3.5.6907.0 (1.23)
3. Make sure the Rollback Option becomes available.
4. „Push” the update process by logging in on 2 or more Tanjays with the same account, but be only active on one of them for some minutes. This will some how trigger the update process and all the devices would be updated within 15 minutes.

strange, but that’s how it works…
