<p>Hello,<br>
</p>
there is a config issue with the Contact alias. It has to be done
only on the Kamailio proxy that is first receiving the SIP message
(request or reply) -- in other words, when Kamailio is the first
node after the end point.<br>
<br>
So Kamailio1 has to do set_contact_alias() only for messages coming
from Asterisk and handle_ruri_alias() only for requests going to
Asterisk; Kamailio2 has to do set_contact_alias() only for messages
coming from UAC (not from Kamailio1) and handle_ruri_alias() only
for requests going to UAC (not to Kamailio1) .<br>
<br>
Otherwise, you can create a local loop in a proxy.<br>
<br>
As a simpler solution, it may work (not sure though) doing
set_contact_alias()/handle_ruri_alias() on both Kamailios, but it
will result on double alias uri parm.<br>
<br>
Also, if there is no NAT between Asterisk and Kamailio1, then there
is no need to do contact aliasing at all on Kamailio1.<br>
<br>
Also, <br>
Cheers,<br>
Daniel<br>
