Item 1.

Security and Issuer.

This Amendment No. 36 (the “Thirty-Sixth Amendment”) amends the initial Schedule 13D (the “Schedule 13D”) filed with the Securities and Exchange Commission (the “Commission”), as subsequently amended, by the Reporting Persons (as defined below), with respect to the L Shares and A Shares of Teléfonos de México, S.A.B. de C.V. (the “Issuer”). Capitalized terms used but not otherwise defined in this Thirty-Sixth Amendment have the meanings ascribed to such terms in the Schedule 13D, as amended.

Item 3.

Source and Amount of Funds or Other Consideration.

The aggregate amount of funds required to purchase the 4,639,500 L Shares purchased by GFI through subsidiaries it controls since September 24, 2007 was U.S. $7,964,649. The funds used to purchase these shares were obtained from the working capital of GFI.

Item 4.

Purpose of Transaction.

In addition to the information previously disclosed by the Reporting Persons in the Schedule 13D, as amended, the Reporting Persons disclose the following recent transaction:

Spin-off

On December 21, 2007, the shareholders of the Issuer approved the division of the Issuer and the establishment of a new independent company called Telmex Internacional, S.A.B. de C.V. (“Telmex Internacional”). The Issuer refers to this transaction as the “Spin-off.” Telmex Internacional will be a holding company focused on international business, providing through its subsidiaries voice services, data transmission, video, Internet access and services related to yellow pages directories. The Issuer will continue to focus on the fixed-line telecommunications business, including Internet access and data transmission, principally in Mexico.

Subject to the receipt of authorizations and the completion of legal formalities, the Spin-off will be implemented using a procedure under Mexican corporate law known as an escision or “split-up.” Pursuant to the Spin-off:

	•	Telmex Internacional will be established as a new company;
	•	Specified assets of the Issuer (including shares of specified subsidiaries) will be transferred to Telmex Internacional; and
	•	Each holder of any class of shares of the Issuer will receive the same number of Telmex Internacional shares of the corresponding class.

Once the Spin-off has been completed, a majority of the outstanding voting equity securities of Telmex Internacional will be beneficially owned, directly or indirectly, by the Slim Family.

Page 16 of 24

The Issuer will not be subject to Mexican income tax on the transfer of assets to Telmex Internacional in the Spin-off, subject to confirmation from the Mexican Ministry of Finance and Public Credit and provided that at least 51% of the aggregate issued and outstanding A and AA Shares of each of the Issuer and Telmex Internacional are not transferred for a period of two years after the Mexican tax authorities have been notified of the Spin-off. The Issuer intends to notify the tax authorities after the expiration of the 45-day statutory period following the registration and publication of the shareholders’ resolution approving the Spin-off, and CGT, a holder of more than 51% of the aggregate issued and outstanding A and AA Shares of the Issuer, has informed the Issuer that it will agree to a two-year restriction on transfer.

Item 5.
