Default SIP-IX does not use "Record-Route:" header

I have tried out Keiichi Honda's "SIP-IX" service, which does a similar numeric-prefix to SIP domain name connection service.
SIP IX -


The SIP INVITE message shown in the dial-a-spiral test shows that sipix.jp does not add the "Record-Route:" header. The SIP-IX service therefore avoids potential problems caused by "lr=on" / "lr".

"Dial-a-spiral" test:

Code:
INVITE sip:050xxxxxxxx@xxx.xxx.xxx.xxx:5060 SIP/2.0
Record-Route: <sip:64.34.173.199;lr=on;ftag=2568014107>
Record-Route: <sip:64.34.162.221;lr=on;ftag=2568014107>
Record-Route: <sip:64.34.162.221;lr=on;ftag=2568014107>
