Which Phone Number Sends the SMS in Sparkforge
Sparkforge picks the SMS sender by priority: the user's assigned number, then the last manually selected number, then the channel number (the first number used with that contact), then the default outbound number. SMS-incompatible numbers fall back to the default.
Sparkforge applies a priority chain to figure out which Twilio number sends an outbound SMS. Knowing the order saves time when a message goes out from the "wrong" number.
Priority order
- User's assigned number — if the staff member sending the SMS is in My Staff with a dedicated number assigned, that number is used. The user can override manually in the conversation.
- Last manually selected number — if the user picked a specific From number on a previous send, the system remembers and uses it next time.
- Channel number — the first number ever used with that contact. Maintains conversation continuity so the contact keeps replying to the same thread.
- Default outbound number — the account-level default, used when none of the above apply or when the channel number has been removed.
Exception: SMS-incompatible numbers
If the user's assigned number is voice-only, the system falls back to the default outbound number for SMS.
How to assign a number to a user
- Open Sub-Account Settings → My Staff.
- Edit the user.
- Expand Call & Voicemail Settings.
- Pick the number to assign.
- Save.
Override on a workflow Send SMS step
Inside the workflow builder, the Send SMS step has a From Number dropdown. Set it to a specific number when you want every workflow message to send from the same line, regardless of staff assignment or channel history.
How to confirm which number was used
- Open the conversation.
- Hover over the SMS message.
- Click the three-dot menu → Details.
The detail panel shows the exact number used to send that message.
