Configuring Multiple SIP Trunks with the Same Provider IP Address

How to configure different SIP trunks with the same IP address?

If the provider has multiple connections with different domains that resolve to the same IP address, you need to:

  1. Specify a unique DID for each provider (for example, risk1, ryb1)
  2. Create separate routing rules for each trunk with the specified DID
  3. Alternatively, you can use different connection ports according to the documentation at Регистрация нескольких учетных записей от одного провайдера [MikoPBX WIKI]
