Josh, Zap pseudo channels and conferences are indeed used in app_rpt:

/* allocate a pseudo-channel thru asterisk */ myrpt->pchannel = ast_request("zap",AST_FORMAT_SLINEAR,"pseudo",NULL); if (!myrpt->pchannel) { fprintf(stderr,"rpt:Sorry unable to obtain pseudo channel\n"); rpt_mutex_unlock(&myrpt->lock); if (myrpt->txchannel != myrpt->rxchannel) ast_hangup(myrpt->txchannel); ast_hangup(myrpt->rxchannel); myrpt->rpt_thread = AST_PTHREADT_STOP; pthread_exit(NULL);

App_rpt uses zaptel conferences and pseudo channels which rely on ztdummy as a timing source. The whole app_rpt application would have to be rewritten to not use zaptel conferences, and new kernel driver outside of zaptel would be required to time the transmfer of the bytes within the conference.

From a quick glance at the code, I don't seen any direct link to zaptel, which means I *SHOULD* be able to modify this code to work under OS X using CoreAudio for audio control.

Since the underlying system on OS X is Darwin (a derivative of BSD), and there is already BSD support in chan_usbradio.c, I think this could work. I already use meetme/etc on my os x server without issues in timing, and I don't see any timer specific code in the chan_usbradio driver..

If app_rpt requires zaptel to be involved, perhaps I can find a way to fix that as well, and open up the os x world to this wonderful utility. I'll keep you all updated...also, Steve, not trying to be argumentative, just making a note :)

Josh,

Yes, they require the use of the ztdummy driver in Zaptel as a timing source.

I was wondering if the usb radio drivers require zaptel (now known as DAHDI) drivers/hardware or if the usb radio drivers can be used standalone? I run Apple equipment here, and I would love to tie my asterisk server (running on my osx server) into my radio, but zaptel is out of the question on this platform.

Any help is appreciated!
