Learn all about VoIP basics, how hosted PBX can benefit your business, and what to keep in mind when switching to a cloud-based phone system. Consider this your VoIP class, where we break down the jargon and show you the myriad ways a cloud phone system can benefit your business. Throughout this section, we try to stay in overview mode, giving you the basics of VoIP as a service rather than detailing specific features of one provider versus another.

 - Танкадо оставил нам только один выход-признать существование ТРАНСТЕКСТА. Такая возможность. Последний шанс. Но мы его упустили. - Не могу с ним не согласиться, - заметил Фонтейн.  - Сомневаюсь, что Танкадо пошел бы на риск, дав нам возможность угадать ключ к шифру-убийце. Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту.

 - И он положил конверт на стойку. Консьерж взглянул на конверт и что-то грустно пробормотал себе под нос. Еще один любитель молоденьких девочек, - подумал. - Ну. Сеньор?.

В тот момент, когда он поравнялся с сиденьем, на котором сидела девушка, и подумал, что именно ей скажет, автобус проехал под уличным фонарем, на мгновение осветившим лицо обладателя трехцветной шевелюры. Беккер смотрел на него, охваченный ужасом. Под густым слоем краски он увидел не гладкие девичьи щеки, а густую щетину. Это был молодой человек.

Дорогие друзья, сегодня я свожу счеты с жизнью, не в силах вынести тяжести своих грехов… Не веря своим глазам, Сьюзан медленно читала предсмертную записку. Все это было так неестественно, так непохоже на Хейла, а список преступлений больше напоминал перечень сданного в прачечную белья. Он признался во всем - в том, как понял, что Северная Дакота всего лишь призрак, в том, что нанял людей, чтобы те убили Энсея Танкадо и забрали у него кольцо, в том, что столкнул вниз Фила Чатрукьяна, потому что рассчитывал продать ключ от Цифровой крепости. Сьюзан дошла до последней строки.

Но Сьюзан трудно было представить себе, что где-то - например, на клочке бумаги, лежащем в кармане Танкадо, - записан ключ из шестидесяти четырех знаков, который навсегда положит конец сбору разведывательной информации в Соединенных Штатах. Ей стало плохо, когда она представила себе подобное развитие событий. Танкадо передает ключ победителю аукциона, и получившая его компания вскрывает Цифровую крепость.
