11.5.1.2. timing device errors
MeetMe requires a timing mechanism. The asterisk software requires an external timer
because it does not have one internally. There are three timing sources that asterisk can
use: a Zaptel interface card, a USB UHCI-compatible root hub, or the "dummy" Zaptel
interface which uses the system clock.
The timing mechanism required by several Asterisk applications is a 1KHz interrupt. If you
are using recent kernels ( > 2.6.12), make sure to check in the kernel configuration, you
selected in processor type and features the timing to be 1000Hz fixed.
Things that require a timing device with asterisk:
- Meetme conferencing
- IAX trunking
- music on hold (not needed, but quality will be better if you have one).
- voicemail and everything that streams audio (not needed but quality will be better if you
have.)
