Here are some useful tips for some of the fields in this section.

Field Description
Outbound CID Overrides the CallerID when dialing out a trunk. This field can be left blank and the caller id of the trunk will be used.
The format is: "caller name" <##########>. Check with your service provider on the number of digits required for the caller id number.
Asterisk Dial Options Do not override the system default unless you are very familiar with the dial options
Ring Time Number of seconds to ring before going to voicemail (ignored if no voicemail)
Outbound Concurrency Limit Limits the number of concurrent outbound calls on this extension, useful as a security tool if this extension has been compromised
Call Screening Requires external callers to say their name, the name is then announced to the user and the user can choose to accept or reject the call
Emergency CID Overrides all other CallerID settings when dialing out on a route tagged as Emergency

Assigned DID/CID

If the extension is associated with a direct DID, enter the DID number in the Add Inbound DID field exactly as provided by the service provider.
