                                EXPLANATORY NOTE

VocalTec Communications Ltd. (the "Company") is filing this Form 20-F/A to amend
certain information set forth in its Annual Report on Form 20-F for the year
ended December 31, 2005, which was filed with the US Securities and Exchange
Commission on April 21, 2006 (the "Original Report"), as follows:

     1. The balance sheet data included in Item 3A of the Original Report
provided inadvertently that the accumulated deficit of the Company as of
December 31, 2005 was $49,546,000. As set forth in the Company's balance sheet
as of December 31, 2005, included in the Company's consolidated audited
financial statements included in Item 18 of the Original Report, the accumulated
deficit of the Company as of December 31, 2005 was $66,952,000.

     2. The last sentence under the header "TAXES ON INCOME, TAX REFUNDS AND TAX
BENEFITS" on page 52 of the Original Report is replaced by "In 2005 we recorded
a tax benefit of one of our foreign subsidiaries in the amount of $19,000."

     3. Item 16C of the Original Report is replaced with the following:

"ITEM 16C. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Our audit committee pre-approval policies and procedures for audit and non-audit
services are referred to in Exhibit 4.1(f) to this annual report.

The auditors of VocalTec received the following fees for audit and audit-related
services in 2004 and 2005 (in thousands of U.S. dollars):

                              Year Ended December 31,
                        ------------------------------------
                              2004                  2005
                        ---------------        -------------
Services rendered       Fees    Percentages    Fees  Percentages
-----------------       -----       ---        ---       ---
Audit (1)                41.7        30%        70        64%
Audit-related (2)         9.5         7%         0         0%
Tax (3)                  66.3        47%        32        29%
Other (4)                23.2        16%         8         7%
Total                   140.7       100%       110       100%

(1) Audit fees consist of services that would normally be provided in connection
with statutory and regulatory filings or engagements, including services that
generally only the independent accountant can reasonably provide.

(2) Audit-related fees relate to assurance and associated services that
traditionally are performed by the independent auditor, including: accounting
consultation and consultation concerning financial accounting and reporting
standards.


                                     Page 4
<PAGE>


(3) Tax fees relate to tax compliance, planning and advice.

(4) Other fees relate to consulting services.

All of the services referred to in clauses (2), (3) and (4) above were approved
by the audit committee of VocalTec.

During 2004 and 2005 Tdsoft paid its accountants an aggregate of $11,000 and
$108,000, respectively. Since Tdsoft was a private-held company, it was not
required under Israeli law to have an audit committee."

     4. The first paragraph under "Property, Plants and Equipment" on Page 40 of
the Original Report is replaced with "Our headquarters are located in Herzliya
Pituach, Israel and occupy 21,500 square feet pursuant to a lease expiring on
April 2007. We currently pay total yearly rental and management fees of
approximately $256,000. These facilities are used for management, marketing,
sales, research and development and production."

     5. The first paragraph under "Compensation of Directors and Executive
Officers" on Page 67 of the Original Report is replaced with "The aggregate
compensation paid to VocalTec's and Tdsoft's directors and executive officers as
a group (prior to the business combination) during the fiscal year ended
December 31, 2005 was approximately $1.76 million and $0.23 million,
respectively, in salaries, directors' fees and bonuses. The aggregate
compensation paid to the directors and executive officers as a group of the
combined company during the fiscal year ended December 31, 2005 was
approximately $30,000."

     6. The first paragraph under "Export Sales" on Page 74 of the Original
Report is replaced with "Export sales of Tdsoft (prior to the business
combination) in 2005 were $3.3 million or 85% of sales compared with export
sales in 2004 which were $2.8 million or almost 68% of sales, and with $2.6
million or 67% of sales in 2003."

     Except for the foregoing, the Company is not amending any other information
set forth in the Original Report.
