IVR: Call transfer failed with Skype

Cannot call transfer, Skype account used is showing a Internal Error 13501. Any ideas why this is happening would be appreciated?

The log file shows: failed transfer to 2140001234 (real number removed) Call transfer failed: Misc error

Looks like you need a 1 in that phone number. In Skype, all US numbers must have 1 as its prefix. Other countries use different prefix, for example, china is 86.

Normally you can also see the error message from the Skype Window.

Thank you that fixed it!
