If "record-route on" is set EVRYWHERE it appears in partysip.conf, then
all ACK will be sent by the UAs to the proxy. If the "record-route" option
is not used, ACK for 2xx must be sent directly to the contact header of
the 200ok received. (which should target to the remote UA!!!). You
can probably change a option in the ATA cojfiguration to get the
correct behavior.

If you use the very latest 0.5.3, you can enable this option to
support CANCEL from ATA186. There is a bug here in the ATA.
# With Cisco ATA (version v2.15 ata18x)
# More generally, if you can't CANCEL calls, try to uncomment this:
disable_check_for_to_tag_in_cancel = on

It is sending it to the incorrect place (depending on record-route mode
used...) I have tested myself an ATA this week and all test were OK
without record-route set. Aymeric
