When you call an IP system through a gateway that requires an extension (E.164 address), enter the extension in the dialing field whenever possible. Check with your network administrator for the extension delimiter you will need to enter into the dialing field. For example, some networks use ## to separate the extension from the IP address.
When you include the extension, you will be given the option of saving both the number and the extension in the directory when the call ends. If you enter the extension after the gateway connects, then you can save only the gateway number when the call ends.
