I usually use high powered Amazon Basics Rechargeable Batteries for most devices.

At one time, I used eveloop but the price difference was too much.

Regarding phones: we have six Gigaset C575A phones linked to the N330a and they work flawlessly.

I cannot comment on the battery life as all of our phones just sit on the chargers until used.

The ones supplied with both Gigaset handsets were no name mystery ones. They recommend Panasonic but don't actually supply those.

I did try some panasonic bright orange ones that are generally used in phones but they were the same behaviour.

I usually rotate mine so they're off the charger until they need charging again. I usually swap them around so they don't get the same usage pattern all the time.

I use Gigaset C530 handsets. I don't know how fully featured they are, but they are compatible.

The manual suggests charging for 8.5 hours and the specification is 14 hours talk time or 300 hours standby time. In my experience that is about right with fresh Amazon Basics batteries. Sometimes I charge them for a few hours longer, but never for multiple days.

After a full charge, the battery indicator stays on full until they are about 75% drained. When I see a handset showing less than full charge, I know it only has a few days of standby time remaining and use that as my cue to recharge it.

It may be bad practice but I have not noticed that just leaving the Gigaset C575A phones on the charger is an issue as we have not noticed any issues in doing this.

Gigaset Guideance does not seem to prohibit this for NiMH Batteries in their cordless phone chargers;

After actually living with the N300 for a bit it's got one big failing. If you lose the internet connection at all it doesn't re-register properly until you reboot it. You can't tell it hasn't either. The dial tone is still on a handset and the blue light on the front doesn't tell you it's not re-registered. It means either having to dial a number and see if it rings or going into the web interface to check. It's a bit annoying.

I think I'm going to get the Yealink system on the A & A accessories page. The supplied handset has a very long talk and standby time so it should be fine with that doing most of the work and the remaining panasonics as fill ins.

Even with a gigaset handset I couldn't access the answerphone to set it on or off so there's definitely some compatibility issues even with gigaset handsets and the N300.

The heading you created referers to the N300a which has an answering machine and I have not had any issues with it.

As I pointed out we use it with six Gigaset C575A handset without issue and these handsets are fully compatable. - (That said, when I first bought the N300a I did try it will my previous Panasonic handsets, (which worked but were dumb), and if you argued that N300a should really work with all makes and types of handsets: I would agree and not all older types of Gigaset Handsets are totally compatible). .

With an N300a and Gigaset C575A handsets; If the internet goes off then there is an orange rectangle message on the handsets to let the user know.

Also; we have two separate VOIP Providers and if either of these VOIP Provers is off an orange rectangle message appears on the handsets.

Sometimes if the internet goes off one of the VOIP Providers needs the N300A to be reset in order to get that VOIP Provider to reconnect but we suspect that is the way that one of the VOIP Providers Reconnects which is not really a hardware issue.

Perhaps, the Yearlink, (which you are buying from AA/ your VOIP provider), will be better for you. - Kindly let us know how you get on.

I leave my Gigaset phones on their chargers and replace the batteries every two or three years. Once in a while I find the voip line doesn’t ring the handset so I just power down and restart the base station.

The N300 A IP re-registration failure also happens randomly and a reboot won't even fix it. The only way to fix it is to change it from DHCP IP to a static with a manual dns address or if it's on that already switch it back to DHCP. Had to keep refreshing the A & A voip page to check or using the status page on the N300 web interface.

Mixed feelings on a few days with the Yealink. No compatibility with DECT handsets of other makes at all. The Panasonics will join the base, ring ok but you can't pick up the call. You can't call out via them either as it just gives you the busy tone. You do get a calling number on the display when it's ringing.

Firmware is Feb 2022 which is rather old and that is the latest. No way of checking automatically on the VOIP box itself as you have to go and download it to a pc etc to update it. Again a bit poor now. When searching for information there were a lot of broken links and the Yealink forum looks a bit dead.

Yealink handset call quality is pretty good though. Not used it enough to find out how close to the 35 hour talk time and 400 hour standby it actually gets. It's been fine all weekend with use and that's already better than any of the Gigaset ones.

A & A pre configured it so it was a complete doddle. Plugged it in and that was it. Handset registered as well.
