Phone Numbers

Every call your voice agents make or receive goes through a number on this page. Settings → Phone Numbers is where you add numbers, decide which agent answers each one, enable SMS, and — the part teams discover too late — monitor whether carriers have started flagging your caller IDs as spam. Like the rest of Settings, this page requires the Manage Settings permission (see Roles and Permissions). The page has three tabs: Phone Numbers (the inventory), Insights (per-number health trends), and Number Pools (caller-ID rotation for outbound).

Adding numbers: Twilio or SIP

Numbers come from two sources:

​

The number inventory

Each number in the table shows: Phone Number · Label · Source (a Twilio or SIP badge) · Region (default US) · SMS (Twilio numbers only) · Voice Agent (which agent answers inbound calls) · Trend (a 30-day connection-rate sparkline that links to Insights) · Created, plus edit and delete actions. Two habits pay off here:

• Label every number by purpose — “Outbound collections VN”, “Inbound support line”, “Campaign pool #3”. Six months from now, a bare phone number in a table tells you nothing, and you won’t remember which one is safe to delete.
• Glance at the Trend sparkline whenever you’re on this page. A number whose sparkline is sliding downward is telling you something — click through to Insights before it flatlines.

Editing a number

The edit dialog covers:

Insights tab: catch spam-blocking early

Carriers silently spam-label numbers that make lots of outbound calls. You won’t get a notification — your calls just stop being answered, because recipients see “Spam Likely” instead of your caller ID. The symptom is a collapsing connection rate on a number that used to perform fine. Revve surfaces this two ways:

1. A warning banner on the Phone Numbers tab when it detects numbers “connecting well below peers and may be spam-blocked.” The banner links straight to Insights.
2. The Insights tab itself: per-number connectivity trends over the last 30 days by default (7- and 90-day windows available).

When you see the banner (or a Trend sparkline falling off a cliff):

1. Open Insights and identify which numbers have collapsed relative to your other numbers dialing similar audiences.
2. Rotate the affected numbers out: reassign their outbound traffic to healthy numbers (or a pool — see below) and rest the flagged ones.
3. Keep the flagged numbers for inbound or low-volume use while their reputation recovers, or replace them entirely if the rate never comes back.

​

Number Pools tab: rotate caller IDs on outbound

A single number making high-volume outbound calls is exactly what gets spam-labeled. Number pools spread that volume: instead of attaching one number to a voice agent, you attach a pool, and each outbound call picks a caller ID from it. The tab lists existing pools (Name · Strategy · Members · Created). Creating a pool takes a Name and a Selection Strategy — currently Random, which picks a member number at random for each outbound call. Pools are attached per voice agent, in the agent’s phone number configuration — see the Phone Number section of Voice Agent Advanced Capabilities. When to use a pool: any agent doing sustained outbound volume — campaign dialing especially. Ten numbers each making a tenth of the calls stay under carrier thresholds far longer than one number making all of them. Combine this with the Insights workflow above: when one pool member starts degrading, swap it out and the pool keeps running without touching the agent.
