Console only linux iax/sip client?

Hi,

I want to use the Console/DSP module as a broadcast service but found the painfully truth that the sound card only has fixed 48000Hz which asterisk doesn’t support and that I cannot add other audio device(it is a Xbox).

I am wondering if there is a SIP/IAX2 console(no X11) client that I can run on it(linux) that serve this task.
