title	Click here to expand what happens if you associate several CallerIDs to the extension.

1. If you have selected more than one CallerIDs for a resource (channel), then the system will send a random one to the public destination.

Example:

Let us assume that the outgoing calls are routed through a resource (channel), Resource #1, for which three public phone numbers have been defined and assigned to the client that owns the extension: 1123, 345876 and 2854478. If you associate all three of them with the extension, when initiating an outgoing call, the callee's phone terminal will display, if it supports the CallerID function, one of the three numbers.

2. If you have selected CallerIDs for more than one resource (channel), then the system will send the CallerID of the resource that routes the call.

Example:

Let us assume that the outgoing calls are routed through Resource #1, for which one public number has been defined and assigned to the client who owns the extension: 2255. You associate this number with the extension and another one, 6987560, defined for Resource #2. If it supports the CallerID function, when initiating an outgoing call, the callee's phone terminal will display 2255.

3. If calls are routed through a resource that does not have a public phone number assigned and you have a CallerID that belongs to another resource set as default, then the system will send the default CallerID.

Example:

Let us assume that the outgoing calls are routed through a resource (channel), Resource #1, for which no public phone numbers have been defined. Your default CallerID is set to 3689, which belongs to another resource (channel), Resource #2. If it supports the CallerID function, when initiating an outgoing call, the callee's phone terminal will display 3689.

Do Not Send not send CallerID on Public Callspublic calls

Applies if you do not want your CallerID to be sent to public destinations. If the callee's phone terminal supports the CallerID function, it will display the Anonymous string.

Send Public public CallerID on Internal Callsinternal calls

Applies if you want the public CallerID (when available) to be used for local and extended local calls as well. It allows the association between the CallerID of the Phone terminal user and an existing card code defined for the same CallerID.

Preserve Original original CallerID on Transferred Callstransferred calls

Applies if you want VoipNow to keep the original CallerID when the call is forwarded between destinations.

Send SIP P-Asserted-Identity and P-Preferred-Identity Headerheaders

Allows the header headers to be added to all outgoing INVITE requests sent from this extension.

The SIP P-Asserted-Identity header The header contains the caller ID number of the extension, e.g. P-Asserted-Identity:sip:0003*003@localhost.localdomain.

The P-Preferred-Identity header is sometimes used to indicate an additional identity of preference when there is a choice.

These headers are preserved only on outgoing external calls, e.g. P-Preferred-Identity: "John White" <sip:johnny@somedomain.org>.
