Call Blocking Phone : Gigaset C620A Duo


Whether you refer to them as Cold Calls or, probably more appropriately, Nuisance Calls, they are unwanted interruptions to your daily living routine. While some of these calls are merely annoying, to say the least, others are more criminal orientated...

Recently I took a look at BT’s solution for dealing with these Cold Calls and now it is the turn of Gigaset, a German manufacturer of telephones, tablets and baby monitors, with the company’s C620A Duo product. As the “Duo” part of the product’s title...

Good, but!

  (Rating Hidden)

I've had the trio set since July 2014. In general they have performed very well but, I've now got a problem where the phones will intermittently cut out during a conversation. It happens on all the phones; the screens also go blank and will only come...

A bit of a disappointment

  (Rating Hidden)

The Which? Full Specification is incorrect as the recording time on the answerphone is only 15mins, NOT the 55 stated - a huge difference! My main issue with this item is that although it does block anonymous calls & withheld numbers, it cannot...

Sound quality not as as clear as the Which report says

  (Rating Hidden)

A phone with good features let down by the sound quality, that isn't to the standard suggested in the Which review. Perhaps we have a rogue example. After a couple of weeks use we're returning to John Lewis for a replacement

A bit disappointing

Having upgraded from a Panasonic quad cordless phone system to the Gigaset 620A quad system I am somewhat disappointed with it.It feels more flimsy that the Panasonic & the navigation button is fiddly. My main gripe is that with the Panasonic if...

Issue with blocking calls

  (Rating Hidden)

Bought this recently as sick to the teeth of nuisance calls & gradually getting used to it. I don't think the sound is that great compared with my 7 yr old previous BT model. The major problem I have discovered is that the blocking of...

Which? response re 'Recording Time'

  (Rating Hidden)

Thanks for your comments. Gigaset and our lab have confirmed that this phone will record 55 minutes of messages. One reason why you may only be getting 15 minutes of recording time is that the recording quality could be set to the highest level...

Recoding Time 15mins not 55mins

  (Rating Hidden)

Purchased this model based upon the Which? review.However, the advertised recording time according to the automated voice control is only 15 mins, not 55mins as stated in the marketing material.Surely this is something that should have been picked up...
