Trunks

Traffic to the Supplier is impossible without establishing a physical Trunk connection.

Trunks are created and stored in the “Trunks” section and are always linked to a specific Supplier.

It is possible to create any number of trunks with different types and settings for any Supplier.

When creating a trunk, the following information is required:

1. Name (can be specified arbitrarily). In the case of creating a trunk for telephony, the name should be specified as follows:
   • Trunk with registration: SIP/login;
   • Trunk without registration: SIP/(name in Latin) (any arbitrary but unique name);
2. Provider (select a specific provider to which the trunk is connected);
3. Trunk type (determined by the traffic transmission protocol);
4. Modifier (specified if the outgoing traffic transmitted through the trunk requires preliminary transformation).

The type of trunk is determined by the protocol over which the traffic is transmitted. Each trunk type has a characteristic set of settings, in the form of fields that appear in the trunk creation form after selecting the trunk type.
