Hi Tim, I'm using OpenVZ, it works very well. Take a look at: http://wiki.openvz.org/Asterisk_from_source You will have to compile dahdi and install it on the HN, and then you compile and install asterisk in the containers. I've not done this with chan_iax, but with meetme. In the case with meetme you would have to move some files over to trick asterisk that dahdi is compiled on the machine. The wiki mentions copying user.h. I used this as a starting point, some years ago: http://www.telephreak.org/papers/vpa/ This paper covers vserver, so it's not exactly the same - but the steps with tonezone was the same when I built the current server running this configuration. I'm in the process of building another server with openvz, so I'll need to refresh my memory and try to document the procedure. -- Med vänlig hälsning Johan Wilfer email: [email protected] JT Tech | Utvecklare webb: http://jttech.se direkt: +46 31 380 91 01 support: +46 31 380 91 00
