Default [Q] DTMF tones

Is there any way to adjust the length of the DTMF tones? My security door at home uses the tone from my keypad to function, like a touchtone system. But Im being told that the tone my phone puts out is too short to trigger the unlock device on the door. Ive seen where other phones can adjust the length of the tone but I can't find any way to do it on the S5. Any ideas?

I dont have that as an option. I have:

Call rejection
Answering and ending calls
Call notification pop ups
In-call status pop-up
Show caller information
Call alerts
Call accessories
Additional settings

Ringtone and keypad tones
Personalize call sound
Noise reduction

Voicemail service
Voicemail settings
Sound
Vibrate

Ive gone through each one of the sub menus available and there is no mention of DTMF tones anywhere.


Oh and I have a stock Galaxy S5 with AT&T running android version 4.4.2

Seems odd that you wouldn't have a basic Kitkat setting like this. Another victory for ATT. It is there on my 900T.

Anyway, install a DTMF app then which will let you adjust the tone length e.g DTMF dialer

Very strange. That seems like an option every phone should have.

Yeah, just about every other phone I know of gives you the option to change it. Thanks AT&T!!

Ive tried a couple of DTMF dialers with no luck yet. Ill keep messing with them to see if I can get one to work on my security door.

The app that I suggested has an adjustable period.

Ensure that you set the duration to long or specify a period. A short DTMF burst is ~ 40 ms. A long burst is ~ 100 ms, although some equipment may be happier with very long tone bursts on the order of 250 ms.

So does this app just work by playing the tones over the speaker into another phone, or does it play the tone into my S5? Basically my security door works where you press my code on the keypad and it rings my phone (my S5). I answer the call and press 9 on the keypad and it sends the tone to the security door and unlocks it. The tone that my phone puts out now is apparently too short for the security door to pick up and wont trigger the unlock. Will this app work where I can answer the call from the security door and then press 9 then play on the app and it trigger the door? Im hoping so!

Go into your Dialer like you're going to make a phone call, type ##3282# and go to Edit in the menu that pops up. DTMF is towards the bottom. You can select short / long in there.

I tried this and the only thing that pops up is "USSD and then my phone number". No menus or anything. Just a button to hit OK.
