Linux Telephony Device Driver

As the title states, i recently brough a CompactPCI telephony box from a now bankrupt ISP but it's current platform is windowsNT. so i need a linux device driver for the telephony cPCI board. The board was manufactured by voiceboard.com. the Superspan Card Model CT28. This is a T1/E1 Card used for VoIP and includes a daughter DSP Card and Superspan Transition Module. This board has reached it's End of Life and Voiceboard will NOT Back build drivers. Will it's just as well, because their drivers & libraries are closed source, and i want to release this GPL. ## Deliverables 1) Linux device drivers for Voiceboard's Superspan Card Model CT28. 2) Complete Intergration with the openDSP libraries ([login to view URL]) and Asterisk pbx ([login to view URL]) 3) I will have Complete ownership and distribution copyrights to all work purchased. ## Platform RedHat Linux Latest kernel!!
