Есть Cisco 1760, никак не получается подключить SIP телефоны сторонних производителей к ней по SIP протоколу, на телефоне статус: "Time Out". Но если, например использовать программный SIP клиент, например на Android, то регистрация проходит успешно и голос работает в обе стороны. Проблема только с аппаратными телефонами.
