We love our listeners outside the US! We have many options to contact us and leave your voicemail feedback;
1. Skype. If you are on Skype, the call is free. Our contact name is jroney. Here is more info: http://www.skype.com/intl/en/features/allfeatures/skype-to-skype-calls/
2. Using a Smartphone to record your audio message. For instance, the iPhone has the Voice Memo app. You can record your feedback and email it to oncepodcast [at] gmail [dot] com.
3. Record an mp3 on your computer and emailing it to oncepodcast [at] gmail [dot] com.
4. Using the website Vocaroo to record your message and email it to oncepodcast [at] gmail [dot] com. Note: Keep in mind, you would need a microphone and (I would suggest) headphones (or earbuds) to record.
5. Purchase an International Phone Card.
Note: These are the only options I am aware of. If you know of other options, please oncepodcast [at] gmail [dot] com with “more International Call options” in the subject line. Thanks!
