Number format | Telephone numbers within Salesforce should be in E.164 format (maximum is 15 digits). For information about the E.164 format, see E.164 format. The format of the number is required for dynamic call routing, screen popping and Click to dial. | ||
| API calls | Your organization must be enabled for API access. You must also operate within the API request limits set by Salesforce for your account. As a guide, each read and each write to and from Salesforce makes one API call. For example, 100 calls make 200 API calls. For information about user permissions required to run API calls, see ContactWorld API user permissions. | ||
| Data requirements | You must have enough Salesforce data storage available for your use. For information about data storage limits in Salesforce, see Salesforce help. As a guide, each call made or received in ContactWorld generates a Salesforce task record. Task records are 2 kilobytes (KB). | ||
| Salesforce CTI | We provide a Call Center definition file for you to import. The imported Call Center uses Open CTI. You do not need to install a CTI adapter. |
