<p>Hi Walter.</p>
<p>you wll probably need to add the alias to make the warning
dissapear. it souns like you don't have the alias <a
href="http://company1.sbc.mycompany.com:5061">company1.sbc.mycompany.com</a> for
the socket, so its complaining, but the message is using the
correct socket for egress from the sound of it. This is what the
new 3.6 feature addresses.</p>
<p>Regards.</p>
<p>Richard</p>

<div>Yes, companies are added in some other system so the
list is dynamic and opensips here is only a SBC without
connections to any outer database. Subdomain is passed in
a custom header and pushed to Record-Route.</div>
<div><br>
</div>
<div>I've done some more testing. There is also a problem
with sequential requests from MS Teams in SIP-to-MS calls.
They come with Route: <a
href="http://company1.sbc.mycompany.com:5061"
moz-do-not-send="true">company1.sbc.mycompany.com:5061</a>
Route hdr and loose_route throws ERROR "Different number
of routes found in msg" because opensips doesn't detect
domain <a href="http://company1.sbc.mycompany.com"
moz-do-not-send="true">company1.sbc.mycompany.com</a> as
local. The problem can be resolved with the domain module
by adding domains to a database. Unfortunately I will need
to sync the domain list in this case.</div>
<div><br>
</div>
<div>In the end I've found that those problems are solved in
OpenSIPS 3.6. It has a new option ACCEPT_SUBDOMAIN on
socket :). But I am not ready to move to 3.6 (3.4 is in
use currently).</div>

Hi Andrew!
<div><br>
</div>
<div>I guess the socket
„company1.sbc.mycompany.com:5061“ is not known to
opensips. Since there is no socket name alias (or is
it meanwhile?) like in kamailio you will need to set
the socket manually. Pls correct me, if Im wrong.</div>

<div dir="ltr">Hi, all<br>
I am working on an MS Teams SBC for multiple
tenants.<br>
I use OpenSIPS without topology hiding so I
add Record-Route headers. For each tenant I
have to add its own domain like
<a href="http://company1.sbc.mycompany.com/"
target="_blank" moz-do-not-send="true">company1.sbc.mycompany.com</a>
and so on. Domains are correctly resolved to
the same IP as
<a href="http://sbc.mycompany.com/"
target="_blank" moz-do-not-send="true">sbc.mycompany.com</a>.
They should be subdomains of
<a href="http://sbc.mycompany.com/"
target="_blank" moz-do-not-send="true">sbc.mycompany.com</a>
. The main domain <a
href="http://sbc.mycompany.com/"
target="_blank" moz-do-not-send="true">
sbc.mycompany.com</a> should also be added
when receiving calls from MS so that they can
send us sequential requests (like BYE).<br>
I use
record_route_preset("company1.sbc.mycompany.com:5061;transport=tls",
"LAN_IP:5060") for that as it's written here
<a
href="https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/"
target="_blank" moz-do-not-send="true"
class="moz-txt-link-freetext">https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/</a>
For calls from MS, I just change the order of
the headers -
record_route_preset("LAN_IP:5060",
"sbc.mycompany.com:5061;transport=tls").<br>
My calls work both ways but I receive the
following warning WARNING:rr:after_loose: no
socket found to match 2nd RR after doing
loose_route() . What are the consequences of
this warning?
<br>
I've already experienced one consequence: when
I receive a BYE, OpenSIPS doesn't set the
socket_out variable, but the actual packet is
sent from the correct socket(or is it just
luck?).<br>
Should I set the socket manually?<br>
<br>
Best regards, Andrew.</div>
