Obi 200/202 with existing Dect phones

[lobsterpasties]

I want to drop my landline and use my existing dect phones with voip.
The 4 phones I have are Siemens Gigaset A120 phones.

I would like to plug the master phone into the unit, so they can be used for voip calls but I have found no confirmation that this is possible with these devices.

My understanding is they act as a single phone would - albeit they have internal communication built in to them. I just want to use them as a single phone would be used.

Thank you in anticipation of any responses

If the Siemens Gigaset A120 analog phones work with your existing PSTN/POTS landline, they should work with an OBi ata configured for VoIP service.  The analog phone side of an OBi connects to regular analog phones (and cordless phones)... one line/extension with the OBi200, two lines/extensions with the OBi202.
