So I downloaded the source for Asterisk last night and attempted to compile it. Everything seemed to run smoothly and no errors were apparent during the install process. I connected 2 IP phones to the server over the network and they registered fine. My problem comes afterwards:
after attempting to call from the console to one of the IP phones as a test, I got the following error
WARNING[9211]: chan_oss.c:485 setformat: Unable to re-open DSP device /dev/dsp: Permission denied
I’ve tried searching through all the different asterisk forums out there, but nothing seems to come up on this issue, and neither do my books.
I don’t know if I did something wrong during compilation or what…
anyone got an idea?
switching to ALSA produced this error:
ERROR[10173]: chan_alsa.c:456 alsa_read: Read error: Resource temporarily unavailable
edit: And crashes Asterisk…
oddly enough, no other program are running that utilize sound, so I haven’t the foggiest idea why it is happening!
So after much trial and error I found the issue: Asterisk 1.6 does not play nicely with Ubuntu.
I originally made the mistake of installing using the default Ubuntu apt-get repos’, which are almost always outdated by 1-2 versions. I updated my repositories with the Asterisk ones and installed version 1.8 and it worked!
