Very interesting! I have xen running on 4 hosts so far. One is a p4 and the other 3 are pentium D. Next build will probably be a dual-dual xeon. I have a few test VM's running asterisk with perl AGI doing cepstral TTS. I first did this about a year ago as a way of exploring the limits of virtualization.
How would you compare asterisk to openser for the master SIP router role? I am about to setup openser on a VM for evaluation purposes. Bryan M.
