CSTA API позволяет управлять вызовами на ECSS-10, устанавливать новые вызовы, принимать/отбивать активные вызовы, управлять базовыми сервисами (HOLD/HOLE, CTR, 3WAY, CONF).

Команды для настройки API (параметры подключения) приведены в разделе /api/ — команды настройки API CSTA.

Протокол CSTA на уровне ECSS-10 работает поверх TCP, как описано в ECMA 323 Annex J.2 (TCP without SOAP). Формат пакета запроса/ответа следующий:

| 0 1 | 2 3    | 4 5 6 7   | 8 . . .          | 
| 0 0 | Length | Invoke ID | XML message body |

Invoke ID :: string(), "0000" - "9999". Invoke ID = 9999 используется в случае посылки событий от ECSS-10 на клиента.
