What happens on deletion

When you delete a SIP trunk:
  • Inbound and outbound trunks are removed from the voice infrastructure
  • Any assistants using this SIP trunk will have their phone number unassigned
  • Any campaigns using this number will have it removed from rotation
  • Call history is preserved and remains accessible
