Why does Siri bluetooth connection in 2008 Toyota Prius with iOS 8 terminate outgoing call with message "call terminated by network" on Prius screen

In years past I did software development for networked computer systems and have been suspecting from the beginning that the root cause was something similar to what you described.

How did you go about submitting an official bug?

The Apple engineer's response inappropriately cast blame on Toyota and dodged ownership and accountabilty on the part of Apple. After all it worked fine in OS 7. Toyota didn't change anything - Apple did.

Systems with two or more computers talking to each other (in this case the car's bluetooth system and the iPhone) are especially vulnerable to this kind of bug. Small errors in timing or the communication protocol between systems can cause a complete malfunction. But that's not the consumer's problem.

Fixing this kind of problem frequently involves painstaking analysis and testing and possibly tweeking parameters that affect timing until a working solution is obtained.

There is no guarantee that Apple's fix in the 8.2 will work. Unless they have a test bed that accurately reflects how them iPhone interacts with the Toyota Prius (incuding the timing of wait states and message passing) they're just throwing a solution over the wall and hope it works.

I'd like to know for sure, too, if it's 8.1.2 or 8.2

I quoted exactly. You register as a developer and bugs are reported at bugreport.apple.com. They said 8.2 and I believe it will be out soon.

I would bet that some of the Apple engineers have a Prius and will test a fix on it. It sounds like it worked by luck on iOS7 and that Toyota is sending something it shouldn't. I can excuse Apple on this type of bug, but not on the many others I have found in Yosemite which have not yet been fixed.

Thanks Nathan for the confirmation there is an imminent 8.2 but I won't "excuse Apple on this type of bug." There is no acceptable reason why it cannot be fixed, particularly when they had working code before. It is purely a lack of diligence on Apple's part. Forget all the unintended obfuscation of timing issues, protocols etc. when you've had previously working code you copy and paste.

This is what I've been doing as a way to use Siri to at least find the number--with my iPhone 5s plugged in, initiate the call with "Hey Siri call ...." The call is dialed but then stopped with the now all too familiar "call terminated by network" message. I then go to recent calls and use that to make the call. It saves a few steps. I've used Siri to text someone with the message "please call me" as a workaround, too.

I'm surprised and disappointed that this hasn't been resolved by Apple yet. It's been months! Before the update to IOS 8, I was able to use Siri to make calls.

It appears that this particular problem only affects Toyotas. Is that the case?

I own a 2008 Prius.

As I replied to a post by Bobbicat on Dec 17th, with the exact same "workaround":

I was using this workaround for a while, unfortunately update v8.1.2 (perhaps even v8.1.1) wiped out this functionality. The last call initiated by Siri no longer appears on the recent calls list.

My experienceotherwisewith v8.1.2 has already been stated by others.

2007 & 2009 Prius, iPhone 6+, 5, 4s iOS v8.1.2

We upgraded 1 of our phones to a 6+, needless to say we won't be doing our 4 others until this is resolved. Nice Christmas/Hanukkah present Apple, NOT!

Lets not confuse the issue for Apple.

BAsed on reading these entries and my experience

1). The issue has nothing to do with the phone you have (other than the fact that your phone may have come with the problem operating system) but is isolated to the new iOS 8 operating system. Even the iPhone 4s have the problem if the phone was updated to the new operating system.

2). The issue isn't isolater just to Prius, but is consistent with ALL Toyota vehicles manufactured in the years around 2008.

I am a big Apple supporter and don't wish negative publicity for them, but this is a big safety issue and should have been dealt with by now. I wonder if we could get Apple's attention to do something quick if we went to the television media (say a "Problem Solver" type investigative reporter) about the phone being sold on the false pretense of hands free use in vehicles via Siri and the danger iPhone holders with older model Toyotas are subject to because of buying the phone???

I am beyond disappointed. This should be the worst problem in my life , but it's an irritant that will either be fixed by the next full IOS version update or some people will jump.

If you work out of your car and use your phone a lot, this is not a tenable alternative even if you want to hang on.

I am seriously thinking that if this isn't fixed by the time the Samsung Galaxy 6 is released I will bail.

Converted from Windows around Vista time and didn't look back. Apple, iPads etc... 100%- today, and it will be difficult to make a move,

It's either that or carry two phones because one day I'm going to have an accident if I continue to use the iPhone 6.

bbeing a beta tester for other products and a previous IOS developer, that is one of the most irresponsible answers I can imagine. Can you please give the full quote with the reply to whoever gave you that nonsense.

ID like to discuss the merits of his/her argument directly.!

same problem here ... first contacted Apple and was told that they were unaware of any issues. Liars!!! Then after spending 4 hours trying to fix they said it must be a hardware problem. Went to Apple and spent another 2 hours to get a new phone. Same **** issue!!!!

I went online and found this forum ... So, they have been notified by all these people! I was just told "oh it's your car manufacturer's problem" ... So, I'm suppose to buy a new car to work with my iphone. C'mon Apple ... GET IT TOGETHER!!!

I am returning my phone! Would love to know if they ever fix in the future ... but for now I'm going to check into Samsung!!!

This is a misrepresentation by Apple to sell this as handsfree when they have been notified of this issue for several months.

Spent 2 hours in the last week in online chat with Apple, without success. Tried all the remedies they suggested. No luck. They told me to take phone to Genius Bar, which I did this morning. Was told they were not aware of any such problem with Toyota, and that they couldn't help me. Said that "maybe it will be in the next update."

Genius Bar manager said "I don't have a problem, but I drive a Subaru." Thanks, that really helps.

What is the make, model and year of your car? What model iPhone do you have and which version of iOS do you have?

Did Apple online support ask you to do a "clean install" (erase the phone completely and reinstall the OS) and did you do it?

I ask only because I'm trying to figure out what to do and what not to do so other users don't waste their time on a dead end.

lexus 2009 GS ... iphone 6 and yes wiped phone clean and did a clean install ... nothing worked ... I'm returning it ... don't have time to waste on this when my 4S worked fine

FWIW, iOS 8.2.0 is supposed to be out in January (it's currently at Beta 3 with devs). There is also rumored to be an 8.1.3 on the way in the meantime, but it's unclear if it has anything to do with this issue or is just a minor bug/security fix ahead of 8.2.

Hello all, as previously posted I also have issues with my iPhone Bluetooth connecting with my Lexus. I have been providing Apple engineers with Bluetooth logs and information. So rest assured they are working on a fix. I am just as frustrated as you all but feel they do care and are working for a solution.
