I am using an AT&T two-line speakerphone, ML 17939. It seems to be dialing just fine, but when I put an extension in, some of the keypad buttons do no work, especially the 3 and sometimes the 4 and 7.
I've tried changing the batteries. That's about all. I'm thinking the keypad is bad. The phone was a couple years old. Maybe time to get a new one, but I thought they could be reset or something
Hello & Welcome, Sorry I didn't see your question earlier.I'm not sure exactly what you mean by "put an extension in". Can you explain a bit more?Also, do the keys on this unit "feel" smooth when you touch them, or do they seem to "stick" when you push them?Thanks
Greg, what I mean by putting in an extension in is after I dialed the primary number, and an extension is needed. Those numbers do not always go in. Or if I'm putting others numbers and such as a passcode to get into a conference call that doesn't always go in. I don't think the key is your sticking I can't feel that.it seems like the number 3 is the worst I've also seen it happen on a 4 and 7Don
Hi again.OK - Usually you can hear a "tone" when you push the keys for these automated services. When you press those keys - especially the 3 key - do you hear these tones and if so do they sound "intermittent" or cut on and off?What I am thinking it that the key contacts could be a bit dirty or worn - especially if the system is "well used" over the years. I do see that these phones are still available (through Amazon), if you would be interested in getting a replacement. I have found that some phones you can get into and try to clean the contacts, but this particular phone is very difficult to get apart and back together successfully, if I remember correctly (haven't seen one in the shop for a couple of years).Please let me know what you hear when you try the "key tone test" or if you have more questions.Thanks, XXXXX XXXXX
