This setting controls the caller ID that recipients see when you dial out. **This applies to:** * Manual dialing from the Allo app * Click-to-dial from CRM integrations (HubSpot, Salesforce, Attio, etc.) * Any outbound call you initiate This setting does **not** affect inbound calls. Routing for incoming calls is configured per number in Settings → Numbers. *** ## How to set your click-to-call number Open the Allo web app at [web.withallo.com](https://web.withallo.com), then click Settings in the left sidebar and select Profile. Find the **Click-to-call number** dropdown and select the number you want to use for outbound calls. All outbound calls will now use this number as the caller ID until you change it again. Tap the Settings icon in the bottom navigation bar. Select **Profile** from the settings menu. Tap **Click-to-call number** and select the number you want to use for outbound calls. All outbound calls will now use this number as the caller ID until you change it again. *** ## When to change it ### Rotating numbers to avoid spam flags If you're making high volumes of outbound calls, rotating between multiple numbers can help protect your caller reputation. Switch your click-to-call number periodically to distribute call volume across your available lines. [Learn about spam flags and caller reputation →](/en/phone-numbers/number-flagged-as-spam) ### Department-specific lines If you handle multiple departments or clients, you can switch your click-to-call number to match the context of your call. For example: * Use your main line for general outreach * Switch to a support line when handling customer issues * Use a dedicated sales number for prospecting ### Testing new numbers When you add a new number, you can test it by setting it as your click-to-call number and making a few outbound calls before assigning it to your team. *** ## Common questions No. Multiple team members can share the same number and still make outbound calls. Each person sets their own click-to-call number preference independently. [Learn about numbers and users →](/en/get-started/numbers-and-users) Not directly at the moment of dialing. You need to change your click-to-call number in Settings → Profile before making the call. A per-call selector is not currently available, but we're tracking interest in this feature. Yes. When you use click-to-dial from HubSpot, Salesforce, Attio, or any other CRM, Allo uses your click-to-call number setting as the outbound caller ID. If you only have one number assigned, that number is automatically used for all outbound calls. You don't need to configure this setting. *** ## Related Add more numbers to your account Understand how numbers and users work together Configure who receives inbound calls Protect your caller reputation
