When using Work for Mobile on iOS devices, calling back an internal extension from the iOS call history will fail because the application tries to add a country code prefix to the dialed number. E.g. After missing a call from extension 131000, trying to call back from the iOS device call history will result in Work for Mobile dialing +61131000.
Calling back from the Work for Mobile call history will work fine.

Change the extension number format and/or the site code so that the numbers do not resemble legitimate numbers.
The iOS device's phone application will automatically prefix numbers that it detects require a country code in front.
The number format that should be avoided will vary from region to region. Avoid extension number formats where the starting digit matches a known valid telephone number of the same length.
