Hello
i manage to fix this. I did not do t_relay() also seq Invites, after
this everything works ok.
Just on question, regarding transfers, i see that MS Teams send REFER in
which trafter is defined. How do you deal with this? You do not allow
REFER from MS teams and hope that MS teams will send new INVITE?
thank you

Miha,
First, do you need to use "mtsbc.test.com:5060
<http://mtsbc.test.com:5060>" in the first record_route_preset()
param? Can you use the IP address of your proxy instead? FQDNs are
legal of course, but outside of MS Teams' implementation, they're
rarely required. It's just another thing to go wrong. Especially
while testing.
The ACK to the 200 OK is a sequential (in-dialog) request. It's not
part of the original INVITE transaction. Your script will have a
section like
if (has_totag()) {
if (loose_route()) {
t_relay();
}
}
for sequential requests through a loose-routing proxy. This is very
oversimplified and yours will have more. In this section, however, is
where you'll process the ACK because it has a to-tag (line 293) and a
route header (line 298) so the conditions match.
Use xlogs or the debug tool of your choice to diagnose what's
happening in this section with the ACK. In my scripts, I use global
flag 0 to indicate when I want logging. So, I might have something
like this:
if (has_totag()) {
if (is_gflag(0)) xlog("L_NOTICE", "...in-dialog $rm
request\n");
# ...do all the things...maybe more logging like the line above...

Hello
I have an issue and I am unable to find out what is wrong.
Incoming calls are working but when doing outbound call after
200OK, which is send to Teams I get back ACK and after that Teams
do again initial. I guess this is not ok.
I am doing this for outband calls:
xlog("L_INFO", "rtp rtps record route");
record_route_preset("mtsbc.test.com:5060
<http://mtsbc.test.com:5060>","mtsbc.test.com
<http://mtsbc.test.com>:5061;transport=tls");
add_rr_param(";r2=on");
I am pasting here trace. Opensips is in the middle.
Thank you for help!
