It seems to work well on Xen without zaptel. Definitely better results than my testing with Asterisk 1.2.1 and ztdummy.
This is what I did: I have a 1.2Ghz Athlon running Xen 3.0.1. There are three domains: Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 616 1 r----- 602.4 dom3 4 256 1 -b---- 67.7 dom1 5 256 1 -b---- 855.2 All the domains are running Ubuntu 5.10 with a Xenlinux 2.6.12 kernel. I have a patch applied to Xen and to Xenlinux that sets HZ=1000. (This is from trying to make ztdummy work in Xen.) I also had Xen's sedf scheduler set to give dom3 a 5ms slice with a 20ms period. I used a checkout of 0.2-beta SVN-1470 running on dom3. I ran a kernel compile with make -j8 in dom1 while makings calls through OpenPBX in dom3. I used a Polycom 501 to call out to the PSTN. The calls were SIP to our carrier. I had canreinvite=no. (We used to have problems with Asterisk doing.) I made 5 simultaneous calls, and set them all on hold with music playing. According to the display on the phone, jitter stayed around 8-12ms, which is pretty normal here. Music sounded good. So I'd say the initial results from casual testing look pretty good. I had audible timing problems just playing hold music on an idle system with the Asterisk setup. ---Nathan Nathan C.
