Local Presence Dialing in the Sparkforge Mobile App

By Sparkforge Support Team ·Last reviewed May 3, 2026

Local Presence Dialing on the Sparkforge mobile app picks an outbound caller-ID that matches the contact's area code (and city, when possible) so prospects see a local number. Set the default once in the web app and it syncs to mobile.

Local Presence Dialing on the Sparkforge mobile app picks an outbound caller-ID that matches the contact you are calling. The app searches your purchased and verified numbers for the closest area-code match — including city-level on mobile — so the recipient sees a familiar local number instead of an unknown one.

Why it matters

  • Higher answer rates from familiar local numbers.
  • City-level precision: the app prefers a city match before falling back to state or country.
  • International support — uses an in-country number when you dial outside the U.S. or Canada.
  • Smart fallback if no area-code match exists.
  • Your web app default carries over to mobile automatically.

Fallback logic

  1. Exact area-code match in your owned numbers.
  2. If none, the number assigned to the user.
  3. If still none, the sub-account's primary number.

The result: every call still goes out, even if a perfect local match isn't owned.

City-level precision (mobile only)

The mobile app drills past the state level to find the nearest city number. A call to a 415 lead in San Francisco tries a 415 number first, then any other California number, before falling back further.

Number Picker for one-off overrides

From the call screen, tap the Number Picker to see every dialable number with assignment tags (user, workspace) and number type (Local, Mobile, Toll-Free). Pick a number for a single call — the system reverts to your Local Presence default after the call ends.

How to set it up

  1. In the web app, open the Location.
  2. Go to Settings → Phone Numbers → Voice → Other Settings → Outbound Call → Default Phone Number for Outbound Calls.
  3. Select Local Presence Dialing.
  4. Update the Sparkforge mobile app to v4.0.0 or later.
  5. Open the app and start calling — Local Presence is active automatically.

Frequently Asked Questions

Does Local Presence Dialing cost extra?
No. The feature is included with your phone-system plan. The only added cost is buying additional numbers if you need broader coverage.
Will it work with my own Twilio account?
Yes. Local Presence selects from the numbers in your linked Twilio sub-account the same way.
What if a contact's area code isn't covered?
The app falls back to the user-assigned number, then the sub-account default. You can also override per call with the Number Picker, or buy a number in that area code.
Can I disable Local Presence for one user?
The setting is at the sub-account level. Individual users can override the caller-ID per call using the Number Picker.
Does it work with SIM-based calling?
No. SIM calls use your phone's carrier number. Local Presence applies only to VoIP calls placed through the Sparkforge dialer.
Are toll-free numbers used automatically?
No. Toll-free numbers appear in the Number Picker but Local Presence won't auto-select them unless they match the contact's country code.
