[SR-Users] Cflag is not getting updated.

[Krishna Kurapati]

I looked at the source code. Updating cflags seems straight forward. I even
did upgrade of
the kamailio to latest. The behavior is the same with the upgraded -the
cflags in userlocation are not getting updated. Also, the received column is
not being set either.

Domain:: location table=512 records=1 max_slot=1
AOR:: p_krishna_test_com
Contact:: sip:p_krishna_test_com at 75.62.17.45:55763;transport=tcp;ob Q=
Expires:: 23
Callid:: 2f34414ed33149cb9ec750d98f311525

State:: CS_SYNC
