Short Answer--Some of the new local access numbers are--the majority are not. The following RingBranch access numbers from the cities and area codes listed below seem to be backdoor eligible at the time of this writing-(you can view the complete access phone numbers after signing up for RingBranch in the Member's Section):
Detroit (313)
Chicago (312)

Some of you may have seen our post from March that described how RingBranch can be used to effectively transform a non-eligible backdoor dialing number into one that is eligible. At the time of that post, RingBranch was getting its phone numbers from a carrier that was interconnected and, as such, our numbers all seemed to be "backdoor eligible." With our new provider, some of the phone numbers seem to be interconnected while most do not at this time. Assuming that you use one of the access numbers from the list above, you should be able to receive a phone call on any of your phones from anyone using Gizmo5. In other words, a person in the US that may have been otherwise unable to receive a Backdoor call could sign up for the free RingBranch service and then be able to receive a free Backdoor call from people outside the US. Let's update the example that we used back in March to show how this is still possible with our new system:
- Assume Jack here in the US wants to receive a Backdoor call on his mobile phone from his cousin Ivan in Turkey.
- Assume Jack's mobile number is 713-555-1212 (just a sample number)
- From Gizmo5, Ivan places the call to Jack's mobile at 01017135551212 (note the 0101 prefix which is necessary to place a Backdoor call).
- Upon making the call, Ivan is notified that the number he is trying to call is not available for free calling at this time. Darn it. But wait, we can help!
- Jack signs up for a free RingBranch account. From within RingBranch, Jack designates that all calls to his RingBranch number should ring through to his mobile phone.
- As a member, he is given access to all of the RingBranch access numbers. Jack determines that some of the RingBranch access numbers are backdoor dialing eligible. So, he tells Ivan to call him on the Chicago RingBranch access number.
- Ivan now calls Jack on the Chicago RingBranch access number at 0101312xxxxxxx. When RingBranch answers, Ivan should PRESS 2 and then enter Jack's mobile phone number. And, moments later, Jack's mobile phone will ring and he and Ivan are connected. The call to Jack that was previously ineligible for Backdoor dialing is now eligilble, allowing free calling from Ivan in Turkey to Jack in the US.
