Setting up a click-to-call campaign on Basis DSP is easy.
When uploading an ad, use the following as your destination click URL: tel:// followed by the phone number (including area code). For example, tel://14165555555.
The number you assign will be dialed immediately when a user clicks on your ad. The number should be entered as the user would be expected to dial it on their phone from the geographic region targeted or the call may not be successfully connected. For North America, this means 11-digit form, including "1" at the beginning of the number. Mobile phones will always accept this format, even if the call is local.
Please note that we do not support premium phone numbers on the Basis DSP platform. For what constitutes a premium number, refer to: http://en.wikipedia.org/wiki/Premium-rate_telephone_number. Additionally, the selected phone number should be matched by your targeted region. If a UK number is listed, the campaign should be targeting the UK.
