I tried to reset the V1 and re-initiate pairing with the iPhone, but didn’t help at all.

I realized what the problem was, and it feels like an iOS5 bug!

I have contacts, in my favorites list, which have multiple phone numbers. e.g. my wife has 2 entries, one for her office number and one to her mobile number. And I’ve got this setup since pre OS3.0 days. So, this is not a new configuration for me. When I do the voice dial, it will not dial the number I’ve set as the favorite, but the first number listed in the contact view. But, if I manually touch the favorites entry, the phone will dial the correct number. So, the portion which allows bluetooth integrated dialing is broken some where.

The workaround is to split the contact into a few contacts. Each with the unique phone number you want to dial. So, for my wife, I have to create 2 new entries, one for office and one for mobile.

This is a really bizarre problem. Hope a fix appears soon.

Blueant V1

About 2 months ago I bought my current favorite bluetooth headset. This is the Blueant V1. This headset has built in noise cancellation, provides voice command and dialing for the iPhone and a bunch of neat voice controlled functions.

When I upgraded my iPhone 3G to OS 3.0, the voice dialing stopped working. My only thought at that time was that the OS 3.0 has changed something and so broke then function between the V1 and my iPhone.

I checked with a friend of mine who recommended me the V1, he had the exact same problem with the iPhone after the upgrade.

Searched around for a bit, but I guess it was too early to find any reports on the net… until today I finally found a forum post of someone having the same issue, and a fix was posted. After reading, I realize I have done almost the same steps, except one, to reset the V1. The forum thread can be found here. Below is the steps I’ve summarized and tried, I eliminated some which I thought should be insignificant.

Hope this is useful for anyone else out there who is experiencing the same problem.

1. Blueant V1 on and connected to iPhone
2. on the iPhone : settings -> general -> bluetooth -> select “blueant v5.3u” -> “forget this device”
3. power off the iPhone
4. on the V1 : press the Blueant button to activate voice command [say] -> “settings menu” -> “reset the V1″
5. power on the iPhone
6. go through the pairing steps between the Blueant V1 and iPhone
7. when completed voice dialing works again
