    Wifi calling- double key presses while in call (HTC Amaze)


      Been using wifi calling on same equip here at home for years which was always a BB until recently when I switched to Android- HTC Amaze. Wifi calling works but whenever I need to press keys to operate a phone system all the presses I hear twice and get heard twice on the other end so entering 1, 2, 3 on the phone ends up 11, 22, 33 on the receiving end.

      I set a QoS rule on my router for the static ip of the phone (which I set) to get highest priority. No effect.

      This issue is not present during non-wifi based calls. Key presses are single and clear.

      It was also never an issue on any of the last 3 Blackberries I owned.

      Any suggestions appreciated.

          Have you tried rebooting phone.

          Hold power and reboot not shut down.

          I don't have that problem with mine also was not able to replicate.

          T-Mobile voicemail system must hate me for smashing on the buttons last time I called it lol

            Yes have pulled the battery and also restarted via power button. No change. Will test on a different wifi connection later today and report back.Thx.

              Tested on diff wifi- same result. :/

              It seems to be an echo sort of as the time between repeats differs from distinct separate tones to almost bumpy tones on top of each other.

                Seems like you've narrowed this issue down to your specific device and DTMF tones, only during WiFi Calling.


                As always, make sure you've got the latest update for your device. Sounds like you've tried the normal stuff, restarting, etc.


                This document addresses a semi-related problem with DTMF tones. Some information in there may be useful to you, but the document doesn't exactly describe the problem you're having.


                Another thing that may help, clear the cache in the WiFi calling app. To do that, just go to settings>applications>manage applications then find WiFi calling, and tap "clear cache".


                As a last resort, you can try a master reset. Of course this erases everything stored on the phone, so please make sure you've backed up important stuff before this so you don't lose anything that you can't get back during the reset. This may help prepare.


                It sounds very unlikely this issue is hardware related, so one way or the other, you ought to be able to reset the WiFi calling app to clear this up.


                Good luck, hope this helps!

                  Hi Chris,

                  Thanks for the info.


                  I am 100% up to date and use MyBackupPro to perform device backups then move those to my computer.


                  Re: clear wifi calling app cache:

                  I cannot clear wifi calling cache as it shows there is none used and all options are greyed out. I also diasbled wifi and checked again.I disabled wifi calling and checked again. I tried to insert a 12KB image but get the following error:


                    You don't have permission to do the requested action. You might need to log in to the system before you can continue.

                     It appears you're not allowed to view what you requested. You might contact your administrator if you think this is a mistake.            "


                  POSSIBLE FIX:


                  The support doc you linked might have actually done the trick. Turning off "audible touch tones" at first test seems to have worked. I still hear the tones I press but I do not hear any echo or doubling.Sweet!


                  This is great because I have no desire whatsoever to wipe my device and if I did I would be looking hard at rooting (wifi/usb tethering would be nice)


                  Thanks very much. If I find the issue resurfaces I will post back here.

                    Hi om_audio


                    You're very welcome.


                    Oh excellent, I use MyBackupPro and have since the G1 days, IMO best backup app on the market.


                    Glad to hear that, hope its cleared up for good. I can appreciate your hesitation to wipe, but at least your backup app will make it relatively easy to restore things after.


                    Please let us know how it goes.


                    Hope this information helps others, in case anyone else comes across this issue in the future.
