DTMF tone “squelching”!

[TID1]

---

The DTMF tones on my EE Homeplus handsets are “squelching” rather than emitting a clear “beep” tone. This causes failure of DTMF tone operated menus etc when using the handset keypad buttons. If I reboot the hub the  tone restores to a “beep” for one use only and then reverts to a “squelch” again. This causes failure of the DTMF tone functionality-very frustrating. EE can offer no solution, I’m hoping that somebody can help me out with this issue?

@TID1 Are both handset's doing exactly the same noise effect?

Hi Jim, they all are - I have 3 and have tried them all after rebooting the hub on each occasion.

@TID1 Would try a couple off them switched off, you are relying on a lower frequency on the dect side so some devices can cause that effect you have, but if you do have one, plug an old landline into the back off the hub and see what it's like when you pick up the call and listen!

You can do the following in a search engine the text is dect frequency range and you will see...

Many thanks - have tried with the old handset hard wired directly to the hub, same result I’m afraid. Will try with only one handset switched on as you suggest. Will keep you posted!

@TID1 With the other handset doing the same it's time to get EE CS involved to look at what is going on with the line connection, text PHONE to 66033 and have EE test the phone system connection out for you!

Thank you, will try them now.
