*  As of August 3, 2006,  Douglass Bermingham  possesses  sole power to vote and
direct the  disposition of 727,934 shares of the common stock,  $0.001 par value
per  share  (the  "Shares"),  of  Altigen   Communications,   Inc.,  a  Delaware
corporation  (the  "Company"),  held by (i) Ten Pine  Advisors  LLC,  a Delaware
limited  liability  company,  the sole member of which  is Mr. Bermingham,  (ii)
several  trusts,  the  beneficiaries  of which are  members  of Mr. Bermingham's
family,  and  for  which  he  serves  as  the  trustee,  (iii)  Mr. Bermingham's
individual retirement account and (iv) Mr. Bermingham  personally.  Accordingly,
for the purposes of Rule 13d-3 under the  Securities  Exchange  Act of 1934,  as
amended  (the  "Act"),  Mr. Bermingham  is  deemed to  beneficially  own 727,934
Shares,  or 4.9% of the Shares  deemed  issued and  outstanding  as of August 3,
2006.  Mr. Bermingham had previously  engaged in certain  discussions with Larry
Bursten,  holder of 70,000  Shares as of August 3,  2006,  with  respect  to the
Company's various  strategic  alternatives.  As a result of such  conversations,
Messrs. Bermingham and  Bursten (the  "Parties")  could have been deemed to have
formed a  "group"  for  purposes  of  Section  13(d) of the Act,  and the  rules
promulgated thereunder, and each of the Parties could have been deemed to be the
beneficial owner of the Shares  beneficially  owned by the other. Mr. Bermingham
expressly  disclaimed  beneficial  ownership of the Shares beneficially owned by
Mr. Bursten.  Additionally, Mr. Bermingham expressly disclaimed any assertion or
presumption that the Parties had constituted a "group."  Messrs. Bermingham  and
Bursten  are no longer  engaged in  discussions  with  respect to the  Company's
various strategic alternatives.





Item 4.   Purpose of Transaction.
          ----------------------

          Item 4 is hereby  amended by deleting  Item 4 in its  entirety  and by
substituting the following in lieu thereof:

          The acquisition of the securities referred to herein is for investment
purposes on behalf  of the Accounts.  Except as set forth below,  Mr. Bermingham
has no present plans or intentions which relate to or would result in any of the
transactions required to be described in Item 4 of Schedule 13D.  Mr. Bermingham
may make further purchases of Shares from time to time and may dispose of any or
all Shares held by the Accounts at any time.

          Mr. Bermingham  believes that the Shares are undervalued and represent
an attractive  investment  opportunity.  Mr. Bermingham  also believes that  the
Company should explore its strategic  alternatives and may benefit from engaging
an investment bank to do so.

          Mr. Bermingham  intends to closely  evaluate the  performance  of  the
Shares,  including but not limited to the continued  analysis and  assessment of
the  Company's  business,  assets,  operations,   financial  condition,  capital
structure,  management  and prospects.  He intends to pursue active  discussions
with the Company's  existing  executive officers (the "Management") with respect
to actions  which might be taken by Management  to maximize  shareholder  value.
Depending upon the Company's financial condition, results of operations,  future
prospects and other factors which Mr. Bermingham deems relevant,  Mr. Bermingham
may, among other things,  (i) communicate with other shareholders of the Company
or persons who may desire to become  shareholders  of the Company  regarding the
replacement of Management  and/or existing  members of the board of directors of
the Company (the  "Board"),  and/or other matters  regarding the  management and
operation  of the  Company,  (ii) seek the removal of one or more members of the
Board  and/or  Management,  (iii)  seek  expansion  of the Board,  (iv)  solicit
proxies,  to  be  used  at  either  the  Company's  regular  annual  meeting  of
shareholders,  or  at a  special  meeting  of  shareholders,  for  the  purposes
described  in clauses (i) and/or  (ii) above or for the  election of one or more
nominees to the Board,  and/or (v) take such other actions as Mr. Bermingham may
determine,  including  negotiated  transactions,  tender offers, proxy contests,
consent solicitations or other similar actions.  In addition, Mr. Bermingham has
retained  the  services  of  Jesup & Lamont  Securities  Corporation  ("Jesup  &
Lamont") to assist in exploring strategic  alternatives,  which may relate to or
may result in some of the transactions required to be described in Item 4.

          Mr. Bermingham may  also interview  candidates to propose for election
to the Board. If suitable candidates are identified,  Mr. Bermingham may propose
such candidates for election to the Board.

          On June 18, 2006, Stephen J. DeGroat, Chairman of Jesup & Lamont, sent
Gilbert Hu and  the rest of the  Board a Letter  of  Intent  ("LOI").  Mr. Hu is
President and Chief Executive Officer of the Company, as well as a member of the
Board.  Pursuant to the terms of the LOI  described  in Item 6 of this  Schedule
13D, as amended, the Buyer, as that term is defined therein, proposed to acquire
all of the  outstanding  Shares  and to  make  the  Company  a  private  entity.
Consummation of the transactions  contemplated in the LOI would cause the Shares
to cease to be  authorized  to be quoted on the  NASDAQ  inter-dealer  quotation
system.





          Following  the  submission of  the LOI to the Company,  Mr. Bermingham
requested a telephone  conference with the Board, Mr. Hu, and Philip  McDermott,
the Company's Chief Financial Officer, to discuss the LOI and specific proposals
Mr.  Bermingham  believes  Management  should  undertake  in  order  to  enhance
shareholder value.  On July 18, 2006, Jason Golz, the Company's public relations
coordinator,  responded via electronic mail agreeing to a teleconference call on
August 3,  2006 (the  "August  3rd  Call").  On  July 25,  2006,  Mr. Bermingham
received an electronic mail from Mr. Golz requesting that Mr. Bermingham provide
certain materials in advance of the telephone conference,  including a letter as
to  Mr. Bermingham's  capacity  to  obtain  sufficient  financing  to  meet  the
obligations of the transaction  proposed in the LOI (the "Comfort  Letter").  On
August 1, 2006,  Jesup & Lamont  issued  Mr. Bermingham  the  Comfort  Letter in
connection with the  transaction.  Jesup & Lamont issued a similar letter to the
Board which was submitted to the Board via facsimile on the same day.

          The only  representative of the Company who participated in the August
3rd Call was Mr. Isaac  Vaughn,  Esq.,  counsel to the  Company and a partner at
Wilson, Sonsini, Goodrich and Rosati P.C. Mr. Bermingham took the opportunity to
explain to Mr. Vaughn his concerns, as well as his desire to help the Company in
developing an action program to significantly  enhance  shareholder  value.  Mr.
Bermingham  outlined  four  specific  points of the program he wished to discuss
with Management and the Board, as follows:

               (1) The Company should retain a nationally  recognized  executive
search firm to provide executive search services for the Company to search for a
new Chief  Executive  Officer  and to  recruit  a more  experienced  and  proven
management  team with relevant  expertise who can devise and execute a strategic
growth plan. Mr. Bermingham suggested that current Management be redeployed into
positions at the Company better suited to each individual's respective skills.

               (2) Two Board  members  will be up for  renewal at the end of the
current  term,  and there is currently an unfilled  Board seat.  Mr.  Bermingham
proposed  filling these three Board seats with Board members whose experience is
more directly beneficial to the Company than that of current Board members,  and
who are  further  removed  from the  Company  in order to  provide  both  better
direction  and  independent  oversight.  Mr.  Bermingham  believes  that  adding
additional  experienced  independent  directors  with no prior  relationship  to
Management  will  enhance  the  Company's   efforts  to  create  value  for  its
stockholders.

               (3) Nearly fifty percent (50%) of the Company's  enterprise value
consists of cash.  Mr. Bermingham  believes  that holding so much cash is out of
line  with the  Company's  peers and that cash is an  underutilized  asset.  Mr.
Bermingham specifically  recommended developing a program to better utilize cash
including,  among other possible strategies, a share repurchase.  Mr. Bermingham
believes that a Share  buy-back would be beneficial to  shareholders  as long as
the Shares continue to be undervalued.

               (4) Pursuant to Amendment  No. 2 to this  Schedule  13D, as filed
with the  Commission on June 20, 2006,  Mr. Bermingham  wishes  to  specifically
discuss with  Management  and the Board the LOI submitted to the Company on June
18, 2006.





Item 5.   Interest in Securities of the Issuer.
          ------------------------------------

          Item 5 is hereby  amended by deleting  Item 5 in its  entirety  and by
substituting the following in lieu thereof:

          Based upon information set forth in the Company's  Quarterly Report on
Form 10-Q for the  quarterly  period  ended  March 31,  2006,  as filed with the
Securities and Exchange Commission on May 15, 2006, there were 14,976,633 Shares
issued and outstanding as of May 11, 2006.

          As of August 3,  2006,  the  Accounts  held an  aggregate  of  727,934
Shares.  Douglass  Bermingham  possesses  sole  power  to vote  and  direct  the
disposition of all Shares held in the Accounts. Accordingly, for the purposes of
Rule 13d-3 under the  Securities  Exchange Act of 1934,  as amended (the "Act"),
Mr.  Bermingham is deemed to  beneficially  own 727,934  Shares,  or 4.9% of the
Shares deemed issued and  outstanding as of August 3, 2006.  Mr.  Bermingham had
previously engaged in certain  discussions with Larry Bursten,  holder of 70,000
Shares as of August 3, 2006,  with respect to the  Company's  various  strategic
alternatives. As a result of such conversations,  Messrs. Bermingham and Bursten
(the "Parties")  could have been deemed to have formed a "group" for purposes of
Section  13(d) of the Act, and the rules  promulgated  thereunder.  Accordingly,
each of the  Parties  could have been deemed to be the  beneficial  owner of the
Shares  beneficially  owned by the other. Mr.  Bermingham  expressly  disclaimed
beneficial ownership of the Shares beneficially owned Mr. Bursten. Additionally,
Mr.  Bermingham  expressly  disclaimed  any  assertion or  presumption  that the
Parties had constituted a "group." Messrs.  Bermingham and Bursten are no longer
engaged  in  discussions  with  respect  to  the  Company's   various  strategic
alternatives.

          Since the  filing of  Amendment  No. 2 to this  Schedule  13D with the
Commission  on June 20, 2006,  the only  transactions  in Shares,  or securities
convertible into,  exercisable for or exchangeable for Shares, by Mr. Bermingham
or any other  person or entity  controlled  by him or any  person or entity  for
which he possesses  voting or investment  control over the  securities  thereof,
were the  sale of 1,400 Shares on July 26, 2006,  at a price of $1.47 per Share,
the sale of 19,000 Shares on July 27, 2006,  at a price of $1.50 per Share,  and
the  purchase of 4,500  Shares on August 7, 2006,  at a price of $1.45 per Share
(each of which was effected in an ordinary brokerage transaction).


Item 6.   Contracts, Arrangements, Understandings or Relationships With  Respect
          to Securities of the Issuer.
          ----------------------------------------------------------------------

          Item 6 is hereby  amended by deleting  Item 6 in its  entirety  and by
substituting the following in lieu thereof:

          On June 18, 2006, Mr. DeGroat sent the LOI to Gilbert Hu,  pursuant to
which,  among other things,  the Buyer expressed a desire to purchase all of the
outstanding  Shares. If consummated,  the transaction set forth in the LOI would
result  in the  Company  becoming  a  private  entity.  Management  and  certain
shareholders  of the Company will be given the option to maintain  their current
pro-rata  ownership.  The LOI is  attached  as an exhibit  pursuant to Item 7 of
Amendment No. 2 to this  Schedule 13D, as filed with the  Commission on June 20,
2006.





          Pursuant to a request from the Company's Board, on August 1, 2006, Mr.
DeGroat,  sent the Comfort Letter described above to Mr. Bermingham,  confirming
Jesup & Lamont's  belief  that the  financial  commitments  can be  obtained  to
complete the  transaction  outlined in the LOI.  The Comfort  Letter is attached
hereto as Exhibit 2.  On the same day, Mr. DeGroat sent a similar  letter to Mr.
Hu and the other members of the Board. That letter is attached hereto as Exhibit
3.

          The descriptions of the transactions, proposals and communications set
forth in this Schedule 13D  Amendment  No. 3 are qualified in their  entirety by
reference to the complete  proposals or  communications  regarding such matters,
each of which is attached to this  Schedule  13D  Amendment  No. 3 as an exhibit
pursuant to Item 7 hereof.

          Except as otherwise  described  herein,  no  contracts,  arrangements,
understandings or similar  relationships exist with respect to the securities of
the Company between Mr. Bermingham and any person or entity.


Item 7.   Material to Be Filed as Exhibits.
          --------------------------------

          Item 7 is hereby amended by adding the following  after the first item
listed therein:

          2. Letter from Stephen J. DeGroat to Douglass Bermingham, dated August
1, 2006.

          3. Letter from Stephen J. DeGroat to Gilbert Hu, dated August 1, 2006.

I certify that the information set forth in this statement is true, complete and
correct.

Dear Mr. Hu:

     Pursuant  to our  letter  dated June 18th,  2006 in which we  outlined  the
