3-Way Call Outbound CallerID: which number shows on a 3-way call

When an agent dials a third party into a call, the person they reach sees a caller ID. The 3-Way Call Outbound CallerID setting decides which number that is. Get it right and your third leg looks trustworthy; get it wrong and your specialist or vendor ignores the ring.

The five choices

This setting defines what is sent out as the outbound callerID number on a Three-way call placed by the agent. You have five options:

• CAMPAIGN uses the custom campaign callerID.
• CUSTOMER uses the number of the customer active on the agent's screen.
• AGENT_PHONE uses the callerID for the phone the agent is logged into.
• AGENT_CHOOSE lets the agent pick a callerID from a list of choices.
• CUSTOM_CID uses the Custom CID defined in the security_phrase field of the list table for that lead.

How to pick one

If your Fronter is dialing an internal Closer pool or an Ingroup, CAMPAIGN keeps the branding consistent and is the usual choice. CUSTOMER is useful when the third party needs to see who the call is actually about, for example a verification line that matches the lead to a record by their number.

AGENT_PHONE makes the 3-way look like it came straight from the agent's extension, which can help when you transfer to a partner who recognizes that line. AGENT_CHOOSE hands the decision to the Agent at dial time, good for floors that route to many destinations. CUSTOM_CID pulls a per-lead number, handy when each Lead has a dedicated callback number stored on the record.

Internal versus external destinations

The right answer changes with where the third leg goes. When the agent dials another Closer or an Ingroup inside your own system, the caller ID barely matters because routing stays internal, so CAMPAIGN keeps things tidy. When the third leg leaves your network to reach an outside partner or a verification service, the displayed number is the first thing they judge, and a recognizable, answerable line is what gets the call picked up.

CUSTOMER deserves a special note. Sending the customer's own number out on the third leg can be exactly right for an identity check, but it also means the third party sees a number that is not yours. Make sure that fits the workflow before you turn it on, and confirm the field actually holds a dialable number for every Lead.

Stay compliant

Picking a number that is not really yours edges toward Caller ID spoofing, which carries legal weight in many regions. Use a number you control and can answer. The goal is an honest, recognizable ID on the third leg, not a trick.

This setting works hand in hand with how the call is routed. If you also need the third leg to ring out through a specific trunk so the agent hears ringback, see our note on the 3-Way Call Dial Prefix.
