}Update a phone number
Assigns an assistant / SIP trunk and toggles inbound/outbound directions. Changing the assistant, trunk or inbound direction re-creates the inbound SIP dispatch rule. Required scope: phone_numbers:write (keys without scope restrictions have full access).

}Authorizations
API key (fam_..., created under Settings → API Keys) or an OAuth 2.0 access token (fam_at_...). REST operations also require API Access for the credential's workspace. Keys can be restricted to scopes such as assistants:read, calls:write, campaigns:write, automations:read, dashboards:read, dashboards:write, leads:write, segments:write, loop:read, loop:write, phone_numbers:write, sip_trunks:write, knowledge:write, voices:read, billing:read, billing:write, settings:write, platform:read, platform:write; a *:write scope implies the matching *:read. Automation and dashboard endpoints also accept the legacy calls:* scope. Keys without scope restrictions have full access within the workspace's available capabilities.
Path Parameters
Phone number ID.
Body
Partial update. When assistant_id, sip_trunk_id or direction_inbound change, the inbound SIP dispatch rule is re-created (or removed). The display-only label can be changed for any phone number owned by the workspace.
Response
The updated phone number.
