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.

Participating in an Encrypted Call

If encryption is enabled on the system, a locked padlock icon appears on the monitor when a call is encrypted. If a call is unencrypted, an unlocked padlock appears on the monitor.

If you are in a point-to-point call or a multipoint call hosted by another system, the padlock icon displays the state of your individual connection.

If you are hosting a multipoint call, the padlock icon displays the combined state of all connections: encrypted if all connections in the call are encrypted, unencrypted if one or more connections in the call are not encrypted.

In one call, some connections might be encrypted while others are not. The padlock icon might not accurately indicate whether the call is encrypted if the call is cascaded or includes an audio-only endpoint. If encryption is required
