Objective Systems Open H.323 for C (ooh323c) is a simple H.323 protocol stack developed in C. The ASN.1 PER messaging code was developed using the ASN1C compiler using a modified version of our core run-time libraries. Additional open source components as well as code developed in-house were added to produce a functioning stack.

The goal is to produce a reusable framework that contains the signaling logic to allow channels to be created and terminated for different H.323 applications. The complexity and unique requirements of these applications make it difficult to create a "one size fits all" solution. We are hoping that releasing this as open source will make it more useful for a wider variety of applications.
