Hi Walter.
you wll probably need to add the alias to make the warning dissapear.
it souns like you don't have the alias company1.sbc.mycompany.com
<http://company1.sbc.mycompany.com:5061> 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.
Regards.

Hi, Walter
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.
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:
company1.sbc.mycompany.com:5061
<http://company1.sbc.mycompany.com:5061> Route hdr and loose_route
throws ERROR "Different number of routes found in msg" because
opensips doesn't detect domain company1.sbc.mycompany.com
<http://company1.sbc.mycompany.com> 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.
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).

Hi Andrew!
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.

Hi, all
I am working on an MS Teams SBC for multiple tenants.
I use OpenSIPS without topology hiding so I add Record-Route
headers. For each tenant I have to add its own domain like
company1.sbc.mycompany.com <http://company1.sbc.mycompany.com/>
and so on. Domains are correctly resolved to the same IP as
sbc.mycompany.com <http://sbc.mycompany.com/>. They should be
subdomains of sbc.mycompany.com <http://sbc.mycompany.com/> . The
main domain sbc.mycompany.com <http://sbc.mycompany.com/> should
also be added when receiving calls from MS so that they can send
us sequential requests (like BYE).
I use
record_route_preset("company1.sbc.mycompany.com:5061;transport=tls",
"LAN_IP:5060") for that as it's written here
https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/
For calls from MS, I just change the order of the headers -
record_route_preset("LAN_IP:5060",
"sbc.mycompany.com:5061;transport=tls").
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?
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?).
Should I set the socket manually?
Best regards, Andrew.
