Hi all,
I tested the following scenario:
astreisk kamailio provider(hostname)
--------------------> dns lookup -------------------->
REGISTER 1 REGISTER 1
<-------------------- <--------------------
401 401
--------------------> dns lookup -------------------->
REGISTER 2 REGISTER 2
(same dialog, increased cseq)
It seems that kamailio does dns lookup again when receiving REGISTER
2, although both registers are part of the same dialog. Is this the
expected behavior?
IIRC now, there is no place in registrar related modules (registrar and
usrloc) where DNS query is done. You have some checks in your config
that caused that.
There is also an option to fetch existing contacts from location and see
if it is an update (matching by call id and cseq) and do directly
save("location").
Cheers,
Daniel
