Points to note about special dialing scenarios:

•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 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 are prompted to save both the number and the extension in the directory when the call ends. If you enter the extension after the gateway connects, you can save only the gateway number when the call ends.

•To place a call within your PBX system, enter the internal extension instead of the full number.

•If you need to insert a pause, add one comma in the dial string for each second you want the system to pause.
