DTMF tones triggered / possible cause VOIP hangup - X Style (Pure) Q&A, Help & Troubleshooting

Hello XDA peeps,
I got a moto x pure 2015 that I bought from NY and I use it with Koodo mobile (Canadian provider) here in Montreal, Quebec. I find that I get quite a lot of false tones being triggered. It's very erratic and I can't find a pattern.
For example, some weeks I will never hear a tone beeping off into my hear. Other weeks, I will hear DTMF tones being tiggered by the voice on the other end. It could be my mom (VOIP) or my dad (mobile sim card) or even when I'm with customer service with a bank or credit card. I read that VOIP is notorious for false triggers because of the coding standards used. I noticed that female voices trigger it more often... in particular my mom.
I also noticed that I cannot hold my VOIP calls for long periods. I ruled out the 30 second VOIP issue as it can be 10 minutes, 5 minutes, or 2 hours before my VOIP call suddenly hangs up. I read that faulty DTMF may trigger the phone to end a call. This happens 99% of the time on different wifi connections (home, work, friends, public wifi, client premises, etc) and rarely, if ever, happens while on 3G/LTE.
1) Does anyone know if there is something that I can do to this phone to make mitigate any false triggers fore DTMF?
2) Can anyone confirm if using a Canadian mobile service on an American model would lead to this false DTMF?
3) any suggestions whatsoever? other than factory reset and changing phones. I did a factory reset already and the moto X pure is the phone I purchased to replace the Note 3 that also encountered dropped VOIP calls. I don't remember the Note 3 having any DTMF issues.

I am confused... Your device does not interpret or use DTMF in any way, and it only generated by the touchpad for "legacy" applications like auto attendants or phone banking systems. If DTMF is being detected on the far end, it is miss registering a minimum of 50ms of two specifically mixed frequencies (Dual Tone Multi-Frequency). The device only generated audible tones for your comfort/reassurance except when dialing digits manually. The phone itself should not be part of the issue here. Also, DTMF is not used as a disconnect signal in any way, audible analog tones for disconnect purposes have not been in common service for over 20 years. And the US and Canada use the exact same North American Tone plan, so in that regard a US or Canadian device is not relevant.
I know this isn't very helpful, but I think your searching for the wrong problem with this "DTMF" thing...
TBH, I have worked in telecom as an enterprise grade VoIP engineer for 25 years, including cellular carriers and hosted VoIP providers, and I have never heard of this issue you are describing.

Hi acejavelin,
Thanks for taking the time to respond. It is quite possible I'm mixing up terms, issues, symptoms, etc. The different issues I'm facing may be completely independent of each other.
The fact is i hear touch tones when no one is pressing on the dialer. not me and not the other caller. some times it's infrquent and sometimes it can be several times in one phone call.
I will research and provide you with references on regarding VOIP/DTMF/call hang ups. Perhaps this warrants breaking down this question into two separate questions.
Will get back to you soon.

Fair enough... but I answered this simply from a cellular carriers perspective regarding cellular service and your device. Not a VoIP carrier, that is entirely different and would depend on multiple things. A traditional cellular carrier and your device would not be the cause of DTMF tones, although if you are using a VoIP carrier or the person you are communicating with is, then that is whole different set of conditions.
Beyond that, standard troubleshooting would apply, eliminate potentials issues one at a time... try different SIM, carrier, destination, etc.... to narrow done to the commonality in every case and then change that piece to see if it eliminates the issue. Not sure what else to say without more information.

so far my testing is indicative that DTMF is the source of the hang ups. I used "in-band" DTMF and it seems that I only hear the tones now without hang ups.

Searched WIKI and posts, think it's posessed

My phone with no change and with every rom is now doing the following.
1. Instead of alarm going off, it calls back the person that last called me at the time the alarm was sapposed to have gone off... sometimes.
2. Calls last call dialed at random often. No specific time of day or number, it just picks a recently dialed or call recieved number, and calls it.
3. Not sure if it's my cheek, but it looooves to put calls on hold as soon as i anwer or in the begening of the call.
4. Any slight touch or fast movement or large breeze over the bottom buttons (mostly noticed on the 4 way) it will call a person.
5. It can never find a 3g network and wants to know if I would like to make a voice cal instead. That's on any call that's not on my sbp favorites.
I know the answer to many other questions, but these are the ones that concern me most that just started out of the blue and i can't find anything other than the mention of one person here saying his phone calls his wife in the middle of the night. I feel the pain.
Any ideas? thinking of going iphone 2.0. Got most the stuff i use and it's stable. But i LOVE the qwerty and would really rather keep this hermes.
Any help is much appreciated.
Thanks everyone,
Joe
oh yeah, and the alarm clock, birthdays, and appts change days and times then go back to the correct times and days. Does this about once a day.
Thanks,
Joe
Ref issues 1-4
My guess is a switch on the D/pad is not releasing correctly/fully and is causing an intermittent contact at the slightest movement or sound. I think you guessed that already.
So anyway - to rule out a software fault you could backup and do a hard reset and test before restoring the backup.
If that fails - assume a hardware fault.
Possible things to check - would require dismantling.
remove the d/pad. Cgeck the buttons for visible movement/any sign of poor contact and release.
If all appears fine then re-assembly will automatically have caused the d/pad connector to be re-seated (another possible cause of the issue - loose connection).
If the problem remains, my best guess for a fix would be d/pad board replacement.

Phone calls drop... BlackBerry Connect the cause?

I bought a TP2 a couple of weeks back; first thing I installed was Blackberry Connect (following instructions on this forum). BBC works perfectly, often pushing email out to the TP2 faster than I get it on the desktop. It's a real winner, pushes PIM info out to Pocket Informant 9 very nicely etc etc. I'm very pleased with the whole set-up.
However, I noticed that the TP2 was regularly dropping calls, both incoming and outgoing. What happens is this: when I make an outgoing call, I dial the number, the calling screen (the one with the dark grey "keypad" key and the red "end call" key) comes up briefly, there are often three quiet beeps and the phone reverts to the green phone screen (the one with recent numbers, the dial pad and the "talk" key). On an incoming call, the answer/reject screen comes up for a second or two with a ringing tone, but before I can pick up, it drops and usually goes off to voicemail. A soft reset seems to cure the problem for a short while, but I was ending up doing a dozen soft resets a day to pick up voicemails and make calls.
After BBC I had installed Kaspersky Antivirus, wondered if it was that blocking calls, turned everything off. No change.
I then suspended the BlackBerry service yesterday and used the phone with no problems (switched BBC on and off several times to check). It seems fairly clear that the BlackBerry connection is somehow interfering with the voice calls.
Any suggestions? Searching the forum hasn't produced anything. No-one on either of the two "BBC working/not working" threads here seems to have encountered this. Dropped calls seem to be an issue on some other HTC models, but no obvious solutions, apart from switching to GSM/manual frequencies. I don't know whether that's the issue here.
Apart from BBC, Kaspersky and PI9, I'm using the machine pretty much as it came out of the box: ROM is 1.19.401.1 (51489) WWE dated 22/6/09 whatever that means. I downloaded a Hotfix from HTC to correct issues with using + in SMS messages. BBC is v.106. I'm on a UK o2 corporate tariff with data and BlackBerry service.
I'm not sure if this properly belongs as a new thread - it doesn't seem to fall within any existing thread, but Moderators please move it if there's a better home.
Thanks very much.
Hi,
I have received my Rodhuim last Wednesday.
From Wedneday to yesterday, I had not problem with phone calls.
I have installed BB connect yesterday evening so I'll let you know if I have the same problem or not.

Thank you. Judging by the lack of replies, this doesn't look like a widespread problem.

Testing Phone Ring

In trying out various ROMs, I've found that with a couple I like the phone will only vibrate and not actually ring. I am aware that there are various settings to check and have done so. My real question is whether or not there is some form of loopback by which one can test whether or not your phone rings appropriately based on your settings. It just gets kind of annoying to have to get someone else to call you to test it and, in my case, I work in a building where by design one can't get cell phone reception so calling my phone from my landline wouldn't work either.

Static on incoming calls when both parties speak

Hello all, I have an EVO running 2.2 stock rooted version .6 along with the latest radios and wimax. The problem I am having is only when I receive an incoming call. Usually it is worst when a ATT Verizon or another sprint user calls me. The issue is a loud static burst when both parties happen to speak at the same time. The static is very noticeable and almost makes it impossible to use the phone. As I said this only happens when I get an incoming call. If I immediately hang up and call that person back presto no static issue. I have tried changing phones, it happens on a BB Tour, Pearl and two Evo's. I have also had Sprint change the MSID several times, and I have even switched phone numbers all to no avail. The advanced tech support team has issued a "network ticket" so I am awaiting the results of that. Anybody have any ideas? heard of this problem? Suggestions, at this point anything would be helpful. I have tried many different settings on the phone and in the ##data# menu all to no avail. So if anybody has any ideas at all I'm all up for trying them.
Thanks,
Ifly
I am having similar issue while speaking with other party who is on VOIP line.
Until I read this, I was not sure whether this is because of VOIP line or is it because of Sprint.
I will try to watch out for this and see if it has any pattern!
I haven't noticed it when I get a VOIP call but I will watch out for that too.

One-way/mono voice conversation issue??

Hi, I have tested and experienced this on three different HD2's, and tried with every radio available in the Master Radio Thread. When talking to someone normally using the internal speaker, and we try to talk simultaneously, on my end the other person's voice completely disappears and I can only hear myself talking. Sort of like the old-style speakerphone effect, where only one person could be talking at a time.
I have tested this extensively with automated voice menu systems as well (like Pizza Pizza) and every time, as soon as I start speaking it immediately cuts off the sound on the other end (the incoming sound from their voice in my ear) either intermittently, so I can only hear brief little bits of what is being said, or altogether so that ten seconds or more go by without my hearing anything at all from the other side (as long as I keep speaking). As soon as I stop talking, I can hear them again, and as soon as I resume speaking, their incoming sound is cut off again.
I am using the Telstra version of the HD2 with the 850mHz band and have tested with a couple of different carriers (Rogers and Bell) with the same results each time. And as I said, I have tried three different units so I don't think it's a matter of defectiveness.
Does anyone know of a fix for this issue?
thats a really odd problem. i can't say i can help much. but i can suggest another keyword that might help you search better for other possible reports of similar issues. at the very least, this word describes your problem a bit more concisely. its called "half duplex".
