Just to double check - have you limited the RTP ports on the asterisk
server to 8000-8019 (in rtp.conf)?

Also, Xlite uses (or used to use) a silence suppresion mechanism that
doesn't work too well with asterisk.  According to the WIKI:

Turn off Silence Supression (to avoid RFC3389 warnings on Asterisk console):
Menu | Advanced System Settings | Audio Settings | Silence Settings |
Transmit Silence: Yes
