Hello, Higher speeds then 9600kbps are not permited by patents.

I always wonder why it would never negociate 14400kbps... when it did work a single page on fine resolution would take 4 minutes. Thank you very much for that link. I knew there had to be more possible configurations for T.38. I will give it a try... but I think I can get away without patching chan_sip.c, no? that just seems to enable higher bitrates. And Linksys SPA2102 is one of the exact devices I have in my lab.
