Hey, thanks for this, I just tried it, it works (kind of)...

But I think it would be much better if app_jack would adapt to the running jack. I sometimes use jack for connecting to a firewire-soundcard and with 8KHz it's impossible to have good sound out of your speakers ;) > > 4) Make a call to the extension created in Asterisk in step 2.

But I can't hear a simple osc~ on the phone, neither can I hear myself on my PC-speakers when I talk into the phone. > > Now, to figure out how to hook up arbitrary jack ports to Pd ... if anyone has > any pointers, it would be much appreciated.

Jack sometimes screws up your system when it runs as root, or other software does, because it has to run as root too. I configured my Asterisk to run as myself, but that's quite complex. Anyway, it's cool you coded all this, thanks. -Chris _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
