Running Asterisk PBX On Linode

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. None of these three timing sources are available on a linode. There are other asterisk features that require a timing source to work.

The timing mechanism required by several Asterisk applications is a 1KHz interrupt. It may be possible to code something that will work on a UML but I suspect it would require mucking about with Asterisk's internals. In any event, you'd want a pretty hefty Linode to run Asterisk for more than playing with. I did have Asterisk running on a Linode 64, but the machine couldn't keep up with more than two connections.
