EXHIBIT 99.1

COSINE STOCKHOLDERS APPROVE PLANS RELATED TO DEREGISTRATION

LOS GATOS, Calif., January 10, 2011 /PRNewswire-FirstCall/ -- CoSine Communications, Inc. (Pink Sheets:COSN.pk - News), today announced that its stockholders approved proposals to amend CoSine's Certificate of Incorporation to effect a 1-for-500 reverse stock split of CoSine’s common stock immediately followed by a 500-for-1forward stock split.  Taken together, the amendments are intended to enable CoSine to deregister its common stock under the Securities Exchange Act of 1934, as amended, and as a result thereof, terminate its periodic reporting obligations with the Securities and Exchange Commission.  CoSine is taking these steps to avoid the substantial and increasing cost and expense of being an SEC reporting company and of regulatory compliance under the Sarbanes-Oxley Act of 2002, and to focus CoSine's resources on the redeployment of its existing assets to acquire, or invest in, one or more operating businesses with existing or prospective taxable income, or from which it can realize capital gains, that can be offset by use of its net operating loss carry-forwards.

Subject to approval by the Financial Industry Regulatory Authority (FINRA) and when effective, the amendments will result in CoSine’s stockholders of record owning less than 500 shares of common stock immediately prior to the effective time of the reverse stock split receiving a cash payment of $2.24 per share, on a pre-split basis, in lieu of owning fractional shares and participating in the forward stock split.  The reverse stock split will be followed immediately by a 500-for-1 forward stock split.  As a result, beneficial stockholders holding shares in "street name" through a nominee (such as a bank or a broker) and CoSine’s stockholders of record owning 500 or more shares of common stock will not be impacted by the reverse/forward stock splits and retain their current numbers of shares of common stock without change.

CoSine anticipates that upon completion of the reverse and forward stock splits, CoSine will have fewer than 300 stockholders of record enabling CoSine to terminate the registration of its common stock under the Securities Exchange Act of 1934, as amended.  CoSine intends to continue to provide interim unaudited financial information and annual audited financial information to its stockholders.

Over 95% of the outstanding shares of common stock of CoSine voted by proxy or in person at a Special Meeting of Stockholders, which took place on January 10, 2011 in San Francisco, California.  Over 80% of the outstanding shares of common stock of CoSine voted in favor of the proposals.

About Cosine Communications

CoSine Communications was founded in 1998 as a global telecommunications equipment supplier.  As of December 31, 2006, CoSine had ceased all its product and customer service related operations. CoSine’s strategic plan is to redeploy its existing resources to identify and acquire, or invest in, one or more operating businesses with the potential for generating taxable income and/or capital gains. This strategy may allow CoSine to realize future cash flow benefits from its net operating loss carry-forwards (“NOLs”).  As of this date, no candidates have been identified, and no assurance can be given that CoSine will find suitable candidates, and if it does, that it will be able to utilize its existing NOLs.
