 Exhibit 10.42 
 PATENT LICENSE AGREEMENT 
 THIS AGREEMENT is made and entered into this 24th day of May, 2006
(“Effective Date”) by and between Vertical Communications, Inc., a corporation organized and existing under the laws of Delaware and having an office at One Memorial Drive, Cambridge, MA 02142 (“Vertical Communications”), and

“a party” and collectively as “the parties.” 
 WITNESSETH 
 WHEREAS, Vertical Communications, previously known as Artisoft, Inc., and a company previously known as Vertical Networks, Inc. (“VNI”) and now
known as Consolidated IP Holdings, Inc. (“CIPHI”), were parties to one or more agreements that related to the acquisition of certain assets by Vertical Communications from CIPHI; 
 WHEREAS, the agreements between Vertical Communications and CIPHI included that certain Vertical-Artisoft Patent Agreement (defined below) that granted
rights to Vertical Communications under certain patents (“C-Data Patents”, defined below) previously owned by CIPHI that CIPHI has subsequently assigned to C-Data; and 
 WHEREAS, Vertical Communications and C-Data desire to enter into a patent license agreement that redefines and restates Vertical Communications’
rights under the C-Data Patents from the Effective Date; 
 NOW, THEREFORE, in consideration of the promises and mutual covenants hereinafter
contained, the parties agree as follows: 
 1. DEFINITIONS. 
 As used in this Agreement, the term: 
  

	 	1.1	“Vertical-Artisoft Patent Agreement” means that certain Agreement between Vertical Networks, Inc. and Artisoft, Inc. relating to C-Data Patents, a copy of which is

	 	1.3	“Licensed Product” shall be defined as set forth in Section 1 of the Vertical-Artisoft Patent Agreement. 

 2. RELEASES AND GRANT. 
  

	 	2.1	Each party hereby releases, acquits and forever discharges the other party from any and all claims related to the C-Data Patents, including any liability for infringement or alleged
infringement by Vertical Communications’ Licensed Products, arising or occurring prior to the Effective Date. The releases in this Section 2.1 are intended to release any and all matters known, unknown, suspected, unsuspected or hereafter
discovered or ascertained with respect to the subject areas covered by the releases in Section 2.1. Vertical Communications and C¬Data expressly, knowingly and intentionally waive the provisions of Section 1542 of the California Civil
Code and any similar provisions of any other applicable law with respect to the subject areas covered by Section 2.1. Section 1542 of the California Civil Code provides: “A general release does not extend to claims which the creditor
does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.” 

  

	 	2.2	Subject to the terms and conditions of this Agreement, C-Data hereby grants and Vertical Communications hereby accepts a non-exclusive, transferable (subject to Section 3
below), sublicensable (but only as expressly provided herein and in Section 2.3 below), worldwide, perpetual, irrevocable, fully paid-up, divisible, royalty-free license to the C-Data Patents to make, have made, use, import, export, sell and
distribute Licensed Products, and to practice any methods or processes covered by a valid claim of an unexpired C-Data Patent, or to otherwise make, have made, use, import, export, sell, distribute, practice or have practiced anything covered by a
valid claim of an unexpired C-Data Patent during the Term. By way of clarification, it is agreed that the license granted hereunder inures to the benefit of the direct or indirect resellers, customers, and other intermediaries and users, of products
of Vertical Communications covered by this license, and to include any third party business interests acquired by Vertical Communications (whether acquired by asset transfer, equity acquisition or otherwise). This License is not terminable by C-Data
for any reason, including a material breach by Vertical Communications of a material term or condition of this Agreement. It is further acknowledged and agreed that Vertical Communications has continuously, and without interruption, had a license in
the C-Data Patents since the date of the Vertical-Artisoft Patent Agreement. 

  

	 	2.3	If within three and one half years of the Effective Date of this Agreement any company that is not listed on Attachment B of the Vertical-Artisoft Patent Agreement threatens to file
or files a complaint or other pleading asserting that Vertical infringes valid patents owned by such entity (such entity being a “Plaintiff’), then Vertical Communications shall have the right to grant a non-transferable,
non-sublicensable, non-exclusive sublicense under the C-Data Patents to the Plaintiff but only in final settlement of such complaint and only to make, use and sell products. Vertical Communications shall have the right to determine any consideration
or compensation terms for the granting of the foregoing sublicense in its discretion and without sharing of the consideration or 

  

 -2- 

	 	  	compensation with C¬Data. Vertical Communications will disclose all relevant terms of the sublicense to C-Data in writing within thirty (30) days of granting the
sublicense. 

 3. ASSIGNMENT. 
 This
Agreement shall be binding upon, and shall inure to the benefit of, the permitted successors and assigns of each party hereto. This Agreement may be assigned or transferred by Vertical Communications to a third party without the prior written

 4. INVENTIONS. 
 VNI, C-Data and Vertical Communications
acknowledge that Vertical Communications may create inventions, trade secrets, improvements, extensions, and/or modifications, based on the C-Data Patents and that any and all such inventions, trade secrets, improvements, extensions, and
modifications, related intellectual property rights (including but not limited to any and all rights that may exist in a specified jurisdiction under patent law, copyright law, publicity rights law, moral rights law, trade secret law, trademark law,
unfair competition law or other similar protections, whether or not such rights are registered or perfected), and any patent applications and patents related thereto, shall be solely owned by Vertical Communications. 
 5. ASSISTANCE OF VERTICAL COMMUNICATIONS PERSONNEL. 
 To the
extent C-Data requires the assistance of any Vertical Communications personnel for the maintenance, licensing, or enforcement of the C-Data Patents, Vertical Communications will be compensated by C-Data on an agreed-to basis. 
 6. WARRANTIES.

represents and warrants to Vertical Communications at the Effective Date that:
