   TELEFONICA CTC CHILE ANNOUNCES THE EXERCISE OF SANTA ISABEL'S ANTICIPATORY
        CALL OPTION TO BUY TELEFONICA CTC CHILE'S 35% OWNERSHIP IN SONDA

(Santiago, Chile - August 1, 2003) Compania de Telecomunicaciones de Chile S.A.
(NYSE: CTC) ("Telefonica CTC Chile" or the "Company") announced today that on
July 31, 2003, the Board of Directors acknowledged receiving notice from
Inversiones Santa Isabel Limitada ("Santa Isabel") that Santa Isabel will
exercise of its anticipatory call option to buy 35% of Sonda Shares. These
shares represent the total stake of Telefonica CTC Chile in Sonda (its former
information system subsidiary).

As previously communicated to the market on September 2002, the Company signed
on September 26, 2002, a put and call option agreement with Santa Isabel for the
35% stake of Telefonica CTC Chile in Sonda, to be exercised in July 2005.
Through this agreement, Santa Isabel also had the right to exercise an
anticipatory call option between July 26 and July 31, 2003, at a price
corresponding to book value as of June 30, 2003, plus a premium of UF 96,000
(approximately US$2.3 million), with a minimum price of UF 1,983,185
(approximately US$47.6 million), minus dividends received by Telefonica CTC
Chile before the date of exercise of the option.

Though the minimum price is established in the put and call option agreement,
the final price is subject to due diligence in order to validate the financial
equity of Sonda. As a result of this transaction, Telefonica CTC Chile will
register a net charge of approximately Ch$6,000 million (approximately US$ 8.5
million) in its financial statements of third quarter 2003.

Upon exercise of the option, the share purchase agreement shall be executed no
later than 30 days of the date of exercise of the option.
