We strongly recommend using E.164 number formatting for all configurations, unless your system has specific limitations.
Examples:
- North America: +14165551234
- International: +862913909201111
SIP Binding Configuration in uControl
When creating a new SIP Binding in the uControl portal, you can select a specific SIP Model Gateway (MGM) that supports E.164 formatting:
- Default SIP MG Model E.164-DM
Note: If your PBX has restrictions that prevent the use of E.164 formatting, we also support 10-digit North American number formatting
✅ 10-digit North American format (e.g., 4165551234)
✅ 11-digit format (e.g., 14165551234) — available upon request
If 11-digit dialing is required, please contact our support team to enable it for your configuration.
