Google Map’s LBC phone validation system has been quirky (also see the old help group) over the years, working for many but failing unpredictably for some. It won’t work with a PBX system and seems to have other limitations but a recent post in the Google Help Fourms seems to indicate that currently, for whatever reason, it just isn’t working that well in Canada.
In a protracted post that started in late January, a number of posters have experienced problems with the system not responding to the phone input. The one common factor between many of the posters is that they reside in Canada. Google, despite there having been 25 replies to this post, has yet to respond in the forum.
Google is the only one that knows when the phone verification system works and when it doesn’t. My suggestion would be to catalog those instances where it is known not to work and detail that information in the help files. It makes more sense than folks sitting in the forums stewing about Google’s lack of customer service. From one of the posts:
I am sick and tired of this nonsense with verification: phone verification does not work, if you are lucky and the system accepts the 1 key then you can’t type the pin code. If you try the SMS then you see the first number of the verification code. THIS IS A JOKE!!
