PanasonicKX-TGP600 SIP Dect Base Unit & Cordless Handset

I bought this new cordless phone for my business thinking it was a good, sturdy and reliable phone. It is completely the opposite. The phone acted strange since day 1. It was not charging, phone just died. When I put it on charge, thinking this would help it did not. It just stopped working. I bought the phone specifically so I could walk around my office and still be able to answer the cordless phone. Could not do that either. If I walked out of the office, which is literally 12 feet away from the base the signal was gone and the phone just died. This phone is not worth the money at all. I will have to purchase a new cordless phone now. Be aware of this product. A new phone should not stop working after less than 8 months. it's a shame you can not buy any quality products anymore. I will never purchase anything from ATHQ again.

I set up my KX-TGP600 late in the evening recently (3 KX-TPA60 handsets and 1 KX-TPA65 desk phone) with VoIP.ms.I'll start by saying that configuration of this phone system and its handsets will require some technology chops. Familiarity with VoIP concepts and terminology is a requirement, and it's probably NOT a good choice for those that think "Vonage Business" is an acceptable and cost-effective solution for business communications needs ;)One of the complaints I read here was that the requirement to enable the embedded web server from the handset was a stupid idea. Of course, the security-minded among us will understand the reason for this feature: you rarely use the web interface, so why leave a potential point of vulnerability permanently available? And if you're NOT going to leave it permanently available (in keeping with good security practices), how exactly would you disable/enable it using a base unit whose only user interface is a single button? Answer: via the handset.Forging ahead... Configuration was actually relatively straightforward; I did not need the administration manual at all. I updated the firmware (wow that took a while), and set up 2 new subaccounts on VoIP.ms (my VoIP provider) for work and personal calls from/to it.The only issue I had with initial setup was that I could not get the phone to register against the subaccounts I'd created unless I used the subaccount name for the "Phone Number" in the SIP settings. This is in agreement with VoIP.ms' instructions for the KX-TGP500, but the problem is that the callerID displayed to the outbound call recipient becomes some portion (in my case, the 2nd through the 6th characters) of the subaccount username. To fix that, you need to set a callerID number in the VoIP.ms subaccount configuration that overrides it.There's also a minor mechanical/design problem (that admittedly will affect very few people) with the KX-TPA65; I use a Plantronics DECT headset (CS361N), which I absolutely love for extended calls. Unfortunately, the TPA65's handset is so top-heavy that the imbalance it creates will cause the Plantronics handset lifter to either completely eject it from the cradle at the middle or high lift settings, or fail to to release the hookswitch at the low setting about half the time.I've worked around the issue by sticking a small amount of some tacky rubber compound at the bottom of the mouthpiece well. This allows the top end of the handset to swing up and disengage from the hookswitch while keeping the bottom firmly in the well.Sound quality is excellent in both directions, and the configuration options for ringers, line availability, button customization and directory management are very useful. It's much more configurable than the Gigaset C610A-IP have out at our vacation home. It's still very early, but I'm quite pleased so far.Update:One thing I was unable to test when I set it up that evening was the receipt of inbound calls (didn't want to wake up the missus). And, unfortunately, they weren't working when I tested the following morning.I checked for differences in configuration between the Panasonic and my venerable PAP2T-NA, and discovered that both registration expiration and Enable 100rel (RFC 3262) differed. One of them fixed the issue (at least for now), but at this point I'm not sure which. I set registration expiration at 180 and 100rel to disabled.Also, voice mail notification via the display wasn't working either, but I believe setting "Send SUBSCRIBE to Voice Mail Server" to Yes resolved that... at least, it's working now.

Phone worked for initial testing when we (IT) set it up for deployment. Once deployed the phone stopped working. When picked up from it's base, the phone does not function, as if it had no power. Tried using anew battery, but the phone would not work.We should have read the reviews before purchasing. The phones seem to die very quickly.

Great phone works well with the other Panasonic system in the office. Fast delivery

Simple setup, good sound quality. Battery life could be better, I’m rarely more than 10 feet from the SIP station so I don’t really understand that, but overall good value.

After almost 2 years of utilizing two of these base units along with 6 handsets, we never could get the system to work correctly. Some handsets wouldn't ring, people couldn't hear us, calls would drop, etc. We finally gave up and bought Vtechs.

Be prepared for A - LOT - OF - WORK.The bad:First - these don't work out of the box with Vonage Business. There are workarounds, and they do work, but MAN. Whoever designed the web interface and more importantly the management doctrine for this handset must have been insane or stupid.First of off, you need to enable the web access for the base station ON THE HANDSET! WTF? Is this to prevent all those cordless VOIP phone hackers I haven't' heard anything about ever?After that you can connect to the webpage. Don't even TRY to use a standard browser. So far it only worked on google chrome AND ONLY in incognito mode because for whatever reason, the page caches your responses and resubmits them everytime the page loads instead of only when you hit the save button.This has SERIOUSLY failed website 101.The wallpaper function is not documented at all (to change the handset wallpaper to a logo) and so therefore doesn't work. No resolution or file type requirements, and no one has a solution via rapid fire google searches.There are SO MANY FUNCTIONS on this phone that are annoying, poorly designed, or just straight up broken. And the latest firmware updates do nothing to resolve this.The good:They have good range, and some of the options are extremely high level power-user type stuff if you have the need for those.If you want basic, easy to use. I recommend steering clear of panasonic.
