DECT 6 Phones’ Major Problems: Dropped and Disconnected Calls. Related to Cable Modem Services?
Symptoms of DECT Failings:
- Call comes in. Pick up on one ring, phone disconnects from base unit, and call is dropped.
- Call comes in or call out. Switch to speaker, call is dropped, phone loses link to base.
I thought it was just me and a bad phone system, but it is not. It appears to be such a widespread problem with DECT 6 phones that many people are complaining about this very issue.
It isn’t just one brand either, or one model of a phone. The problem is so pervasive that Panasonic has a set of instructions on how to “fix” the disconnects and dropped calls:
Verify if the phone cord is connected directly from the base of the phone to the wall jack. Remove any accessories such as Caller ID Boxes, other phones from the same jack, splitters, couplers or T adapters.
Change the line mode of the unit using the handset. Please follow the procedure below.
1. Press MENU POUND, and then 122.
2. Set the line mode to B if it is on A or set it to A if it is on B.
3. Press SAVE, then OFF.
As a last option, please move the phone to another known working wall jack and replace the phone cord, and see if the phone works there.
The problem with this fix is that it may work for day or two but the problem just reappears. I bought this set of Panasonic KX TG9333T in 2003 and it has been nothing but trouble for me. I have replaced one, two, and then entire set under warranty with Panasonic. They do not know what the cause is nor how to fix the problem. I had to replace one phone because the battery burned up inside. As I read the consumer complaints on Amazon, there still is no fix for this issue, but DECT phones are now just about all you can buy in the stores.
Interestingly, I had no problems with a Panasonic 5.8 GHz phone that I used for several years, until I wore out the earphone jack.
Are Cable Modems, DSL Modems, or VOIP/Internet Phone Services to Blame?
I raise this question, because there isn’t really any statistic on which type of phone services people have who are also having this disconnect issue. It could be that the problem is only manifest on homes that are using cable modems, DSL, and/or Internet phone service companies like Vonage.
If you are having a problem with DECT phones and are/or are not on VOIP, please comment.
