1075699 - Calling voicemail by long-pressing the 1 button displays an error and then calls. (Error dialog persists & must be dismissed after you hang up.)

Status: VERIFIED FIXED

(Firefox OS Graveyard :: RIL, defect)

Description

[Doug Sherk (:drs) (inactive)]

STR:
Long-press the 1 button on the keypad.

Expected:
Call placed to voicemail.

Actual:
Error message displayed, then call placed to voicemail shortly thereafter.

Frequency: fairly often. I thought I saw this on master recently, but I think I had entered numbers into the keypad before long-pressing 1. Daniel says that it repros on 2.1 consistently.

Comment 1

[Daniel Holbert [:dholbert]]

Yup, this happens 100% of the time for me, using a 2.1 build on my flame (regardless of whether I've entered numbers before the 1).

Also: when you end the call (and the "in-call" screen goes away), you're left looking at the error message. You have to dismiss it by hitting "OK" before you're returned to the dialer.

The error message says:
 Unable to make a phone call now
 -------------------------------
 Cannot make a call. If you
 are already dialing, please
 hang up first.

dbaron can reproduce this in his 2.2 build, too. (I just had lunch with him & he tried it while sitting next to me & reproduced it.)

(We're both on T-Mobile -- that might be a factor here.)

Comment 7

[Tamara Hills [:thills]]

Hi Hsin-Yi,

I did some debugging on this and found that we are getting an unidentified error back in the telephony_helper.js when we dial the T-Mobile VM number (123) from a T-Mobile SIM.  

I turned on the ril debugging and compared dialing a 3 digit # 411 (our information number here in US) to dialing 123.

I'm seeing one error 19 come back when we do a REQUEST_DIAL.  I cut out a ton of lines, but basically, the sequence goes like this:

I/Gecko   ( 8856): RIL Worker: [0] Received chrome message {"number":"123","isDialEmergency":false,"isEmergency":false,"rilMessageClientId":0,"rilMessageToken":21,"rilMessageType":"dial"}

I/Gecko   ( 8856): RIL Worker: Outgoing parcel: 0,0,0,32,10,0,0,0,21,1,0,0,3,0,0,0,49,0,50,0,51,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

I/Gecko   ( 8856): RIL Worker: New incoming parcel of size 12

I/Gecko   ( 8856): RIL Worker: Parcel (size 12): 0,0,0,0,21,1,0,0,19,0,0,0

I/Gecko   ( 8856): RIL Worker: [0] Solicited response for request type 10, token 277, error 19

Do you happen to know what the error 19 is?  I attached the full log for both working (dialing 411) and non-working (dialing 123).

The call does seem to be established, despite throwing this error.  Not sure if there is something specific to do with TMobile's network or not.

Also, as a side note, is there a place I should look for all the parcel layout definitions?

Thanks,

Hi Tamara,

When REQUEST_DIAL fails, we will retrieve the call fail cause [1]. Per the log you provided, the last fail cause is 246 (i.e. CALL_FAIL_DIAL_MODIFIED_TO_DIAL [2]). As we don't have this value in our mapping table [3], gaia will get "unspecified error." But note that we didn't have this value in v2.0, either [4] so this "unspecified error" doesn't look like a root cause. We probably need to compare the messages b/w v2.0 and v2.2. Can you attach v2.0 log with ril messages?

Also, according to the log, seems T-mobile has STK call control for the number 123. That's why not everyone (every carrier) hits this issue.

=== log snippet ===
I/Gecko   ( 8856): RIL Worker: Parcel (size 20): 0,0,0,0,22,1,0,0,0,0,0,0,1,0,0,0,246,0,0,0

Hi Hsin-Yi,

Thanks for your response.  I did some more testing and realized that the error is coming in earlier versions on the flame as well.  I'm seeing the error on all versions of the flame back to 1.4, but I'm not seeing it at all on the Hamachi (I checked 1.4 and 2.2/master).

The switch is telling us to translate 123 -> 18056377243 because they are load balancing the Voicemail servers.  On the Hamachi, I see that 123 number get translated to 18056377243 in the UI, but I don't on the flame.  

I'm going to try Doug Sherk's suggestion and update one of my flames to kitkat and see if that has any impact.

I will try and catch you late tonight my time to see if we can look at this together and take some help from you if that's ok.

Thanks,

[Hsin-Yi Tsai (she/her) [:hsinyi]]

1st, I think I'd need to step back a little to confirm the observed behaviour again. Per comment 1 and comment 7, the voicemail call was correctly made and displayed on callscreen but there's a problem with weird call error message, right? If I misunderstood the issue, could anyone please attach a video for clarification?

2nd point is, this issue results from different hardware behaviour, reproducible on Flame but not on hamachi. This doesn't seem a regression but a device behaviour issue. On hamachi, modem/rild returns a successful REQUEST_DIAL even a call number is modified by STK. Later, a call with a new number is notified. However, on flame, when there's STK call control, modem/rild returns a failed REQUEST_DIAL with error "CALL_FAIL_DIAL_MODIFILED_TO_DIAL (246)". Also, the call number coming with following call state change events is still "123" (not modified). I am wondering if the modem behaviour is correct or not. May I have your input here, Michael? Thank you!

3rd, we could think about having a specific error message for "CALL_FAIL_DIAL_MODIFILED_TO_DIAL" as CAF does to avoid confusing users [1]. But not sure if this options resolves my 1st question.

Hey Michael, 

One more question about the meaning of the error code: when gecko receives CALL_FAIL_DIAL_MODIFILED_TO_DIAL error, does that mean the modified call is already made successfully, and we can expect a call state change event for the call comes? Or, the error just tells that STK redirects an original number to a modified one, and the modified call might fail? Thank you.

Hi Viral,

Do you know how to get qcril onto a flame device?  I've tried full flash and that seems to install mozril. tchung suggested that you might know how to do this.

Thanks,

Comment 15

[viral [:viralwang]]

Yes I do know the answer but, sadly, the answer is we can't build our own gecko with qcril.
The only qcril we can have is the base image v184 that partner provide and I don't think it can really help you on this bug :(

Attachment: Gecko Patch

Hi Hsin-Yi,

I've added an errorcode for us to recognize in Gaia.  I had few questions:

1. I tried to keep the variable name inline with rest of the ones in ril_consts.js but that caused me to have to adjust the spacing.  Let me know if you want a shorter name (which doesn't quite fit with the convention) or you want me to wrap just that line, or as-is.

2. Looking for some feedback on what test suites this should be included as I didn't see the other error codes in testing, but maybe missed something.

I will have gaia portion ready shortly.

What you have in the patch looks good to me. We can leave as what it is now.

You are right. We don't have a specific test case for error codes.
I think we can have a new xpcshell unit test to cover this new error code.
In that test case, we should write a fake .sendRilRequestDial() and fake Buf.readInt32(). [1] is a good example.

Per comment 19 I'm pretty tempted to remove the 2.1 nomination, not a regression and specific to the flame. But will wait till Doug and Tamara give their opinion here.

We should put this error at the beginning in handleError, to make it more explicit:
// We ignore this because "to explain"
if (errorName === 'ModifiedDialError') {
  console.log('ModifiedDialError');
  return;
}

Also in the test, you don't want to add ModifiedDialError to the expectedErrors array.

Other than that, this looks good.

(The transition from the dialer to the call is pretty fast, and I could believe that it skips past the error message in some conditions, even when it's reproducing.  A better test: do you see the error screen *after you hang up*? [it sticks around until you dismiss it, per comment 2])

Comment 36

[Cody Roesch [:croesch]]

Hey all,
    So I went back and checked the bug on V184 base with T-Mobile sim with Flame. Holding the 1 button down to access vmail on the Dialer pad then hanging up I was not able to see this error message out of 20 attempts. 0/20.

I then decided to try the recent call log and just tap on the number and make the call. Again I was not able to get the error message to occur. 0/5 attempts.

So then I decided to use Impatient user mode and rapidly tap the recently dialed number for the VMail. I finally AM able to get this error to occur on both the dialling and the after hanging up. I had to dismiss the error as decribed in comment 35.

This is different than how I was able to just hold down the 1 key to access the VMail on the dialer pad in other builds.

Apologize that I did not see this before but I did not try aggressive mode last time.

Attachment: New PR with rebased changes to fit into 2.1

Hi Doug,

I'm guessing we need a re-review since the code is now in different files.

This is the Gaia portion put into telephony_helper.js instead of telephony_messages.js (as telephony_messages.js refactor is not in 2.1).

Note that I don't believe the Gecko portion is in the nightly build just yet, so I've not tested end to end with the nightly that has the gecko portion.  I'll make sure to test that when I get the next nightly build.

I'll leave the NI on myself until that is done.

New PR with rebased changes to fit into 2.1

Generally, uplifts don't require review unless the patches are wildly different between branches. In this case, the code is identical, but in different files.

I would like to note that I think the summary on the PR could be better. While this fixes an issue for T-Mobile users, it could definitely impact others as well. We just haven't found any yet. It's also unspecific about what is being suppressed.
