Each year in August there is an open source telephony developer's conference called ClueCon. We encourage all those who use open source telephony to support this great conference by attending or sponsoring. This conference offers a unique opportunity to personally connect with the primary developers of projects like FreeSWITCH, OpenSIPS, Kamailio, OPAL, and more.

OSTAG is pleased to announce that we have officially received word that we are now a 501(c)(3) non-profit corporation under US law. A special thanks goes out to Melanie Clark for her amazing efforts in this process. In addition to filling out numerous forms, and replying over and over again when the IRS came back with questions, she also met with IRS representatives on more than one occasion. Without her hard work and experience in such matters we would not have made it. Thank you, Melanie!
