Choose how calls go out
Outbound routing → Choose how calls go out: pick which calls (all of them, a country, or numbers starting with certain digits) and which of your provider’s options they use — Standard, Premium, Call Center, or whatever your provider offers — with an optional backup if the first cannot connect. A country or a start of a number beats “all calls” for the calls it covers. Try a number shows how a call would go before you save. You choose among the names your provider offers; which carrier carries each is theirs to manage. Your choices appear in the list with a remove button. Changing a choice. Use the pencil on a choice to switch it to another of your provider’s options, or remove it. The operator can edit any rule in place: its numbers, which organisation it’s for, each leg’s carrier and service level, and whether a leg is used at all. The list follows the organisation chosen in the page header. It shows that organisation’s own rules and the shared rules that apply to it, the same ones its calls use. Only what you choose is used. A call goes through the option its rule names, and fails over only to the backup you chose. A number no choice covers is refused, with a message to the caller, unless your organisation has a trunk of its own. To set a default for every number you haven’t covered, choose All outgoing calls.Outbound
A trunk group orders your organisation’s own carriers, and they are used only for numbers none of your choices above covers. Within the group: a carrier you supply yourself comes first, then the order your provider set, then the cheaper one — price decides between carriers of equal standing, not over them. The operator’s shared carriers are used only through a choice above, never by default.A trunk you supply yourself is preferred over the operator’s, and it is tried
even when your balance is empty — those calls cost the platform nothing, so
refusing them would be charging you for the privilege of using your own
carrier account.
