Entering number with 1 (country code) loses final number

[Devpaq]

Many people enter their phone number including the initial 1 (ex: 1-212-123-4567)
If someone does that it will only take the first 10 digits and drop the last digit.
Is there any way to set it to remove the initial 1 if they start the number with 1?
