Thanks for the testimonial.

FreePBX claims to be a nice web gui for Asterisk, that's why I asked about it.

Thanks for the reassurance. I've just ordered a vpslink Xen guest but
the ssh latency from my home is very slow (I'm actually connected
through a pretty good ISP). I'll try it from work tomorrow.

Is 200ms ping time too much for SIP, or is it irrelevant.
Very relevant. Callers usually notice roundtrip voice delays of 250ms or more.The recommendation for VoIP is a one way delay of less then 150ms. Anything more will become very noticeable in conversation and in real life 150ms is too high as well since jitter before induce around 10ms addtional latency.

In your case, 200ms round trip time, assuming a symmetric distribution, of delay (but mind you that the internet isn't really symmetrical...) is 100ms one way delay so this is not excellent but not really bad either. In theory, at least, you shouldn't be able to notice this delay in conversation.
