Most likely an XLite/local sound (driver etc) related problem. I'm
currently testing XLite on linux, and especially the XLite buffer
parameters have quite some impact on audio quality as well as latency,
in a tradeoff sense.

You could try other softphones, like SJPhone, and compare. If there's
a notable difference, try to tune XLite in case you want to use it, or
just use the phone which works best.

Look here for a extensive list of hard- and softphones

Also, it's always beneficial to tell us the OS you're working and having
problems on (Windows, Linux, etc), since e.g. XLite on linux is still
beta.
