We cannot get the Expansion modules to connect to the Aastra Color 6739i phones! We must be missing something obvious here. We have tried 3 different modules, 12 phones, 3 firmwares etc.. Please help!

AC Power needed!

Hi,

With the 6739i, you need to use the AC Power Adapter (sold as optional part - same adapter as used for the 675xi phones) if you use expansion modules.
