International Call Dialing Delay

The last two digits maps you provided both accomplish the same thing but go about in a different fashion?
Correct

I take it the second digit map provides more room for creativity and configuration in not needing to have such lengthy digit maps?
I included the 2nd example to show you how to reduce the size of the digit map

To confirm, the digit map with the question marks is a simplification of the one above it; any number preceding the question mark is optional meaning that at least 11 digits must be dialed before the number is accepted--12 digit or 13 digit international phone numbers may also be dialed with 13 digit numbers be the maximum that will be accepted?
Correct

If I were to be unforgivably lazy, using 011xxxxxxxxxxxx.S4 would require a minimum of 11 digits but would also allow numbers exceeding 11 digits to be dialed, only it would also allow numbers of invalid length (20 digits, for example) to be dialed?
Correct

I ask your forgiveness of the peppering of questions.
You are forgiven

After some further pondering over spring break, I've decided to implement the abridged variable digit map which implements question marks. At first I had my doubts that I'd be able to craft a proper and fully functional digit map, but I believe I've squared everything away and am seeking confirmation.
Thus far I've developed and instituted the following digit map: 011[1-9]xxxxxxxxxxx?x?x?x?S4
If I've done things properly, and understand our previous discussions, the above will require at least 11 digits before doing anything with the dialed numbers. Anything numbers less than 11 digits will be be replied to with a rapid busy signal.
According to the ITU's specifications/recommendations (E.164):
Quote
Plan-conforming numbers are limited to a maximum of 15 digits, excluding the international call prefix.
Because of this, my digit map is configured such that numbers ranging in length from 11 through 15 will be accepted. (I'm nearly certain that 10 digit phone numbers belong exclusively to the North American Numbering Plan.) Numbers with lengths of 16 or more digits will not be accepted and should receive a rapid busy signal.
Near as I can tell, there do not exist any country codes (not exit codes like 011) that begin with a zero. For this reason, the inclusion of the [1-9] will also invalidate dialing 011 + 0.
I'm hopeful my understanding and implementation of the above digit map is correct and welcome hearing from anyone with knowledge on the subject. Here's hoping I'm not too far from the mark!

Even though it's been a while since last there was an update here, instead of creating yet another post I'll ask two additional questions I have that are closely related to the original discussion.
1) Does Google Voice/Chat accept international phone calls prepended with the U.S. exit code of 011? I've taken notice of several VoIP providers that don't need the 011 to route the international calls and the digit map needs to be configured to strip away the 011 before sending it to the service provider.
2) Even if Google accepts international calls with the 011 preceding the country code and other digits, just for my own edification, how would the digit map be altered so that the 011 would NOT be passed on the service provider (ex. dialing 011 44 161 794 5559 would be sent to the SP as 44 161 794 5559).
Again, my apologies for taking to a "dormant" topic to ask something else, but all the questions are very closely related. Hopefully the second of the two questions require just a simple modification to the digit map.

1. GV requires the 011 prefix for calls to numbers outside the NANP area.
2. Stripping the international call prefix is done just the same way as removing any other leading digits. For example <011:>44xxxxxxx. as part of the relevant rule in the OutboundCallRoute.
Steve56:
Thanks for the response and suggested outbound call route. After further reading, it seems using my original outbound call route "command" of "011[1-9]xxxxxxxxxxx?x?x?x?" is unnecessary. Instead, something similar to what you've suggested like "<011:>xx." would be all that's necessary to strip away the 011 from any and all numbers dialed with one or more digits dialed after the 011. Is my understanding and application of outbound call route correct?
Conversely, if I wanted to prepend a set of digits to a dialed phone number, can that be accomplished through the outbound call route or the digit map? If so, I take it the correct syntax would be "<011>xx." or similar ("<011>xx." would then prepend 011 to any number dialed with one or more digits.)?
