Cisco IOS routers have shipped with voice interface cards since , and after this capability was available the term voice gateway became part of the VoIP vernacular, seemingly overnight. The voice interfaces allowed routers to provide a critical interconnectivity link between the traditional data IP networks and the traditional voice PSTN, PBXs, and key systems networks. With this technology, the industry widely built toll bypass networks during the late s: Enterprises connected their PBXs at different sites with VoIP "trunks" instead of with TIE lines or the PSTN, and service providers leveraged IP backbone networks to offer calling-card services and cut-rate long-distance and international calling.

Джабба презрительно хмыкнул. - У вирусов есть линии размножения, приятель. Тут ничего такого. Сьюзан с трудом воспринимала происходящее. - Что же тогда случилось? - спросил Фонтейн.

 Это тебе велел Фонтейн? - спросила. Бринкерхофф отвернулся. - Чед, уверяю тебя, в шифровалке творится что-то непонятное.

Почему вы не дождались полицейских. И не отдали кольцо. - Мне много чего нужно, мистер Беккер, но неприятности точно не нужны. Кроме того, тот старик вроде бы обо всем позаботился. - Канадец.

Не снижая скорости, мужчина указал Беккеру на двустворчатую дверь и скрылся за поворотом. Беккер последовал в указанном направлении. Он очутился в огромной комнате - бывшем гимнастическом зале.
