connecting NATed endpoints with MS servers).
You need to populate proper Record-Route headers in the initial INVITE
as explained int the blog:

Thank you for reply,
I fixed Contact header in ACK, but Microsoft still unhappy call drops after 20 sec.

Onderwerp: [OpenSIPS-Users] ms teams ACK
Hello Everyone,
Is possible rewrite ACK contact header in dialog ?
My guess it expecting FQDN.
MS Teams disconnect the call after 20 sec
REASON: Q.850;cause=18;text="bc427610-edae-47b9-9daa-7ea74d40dcc7;Call Controller timed out while waiting for acknowledgement."
In this case ACK come from asterisk box.
Opensips Log:
/usr/sbin/opensips[3321]: [IN-DIALOG] [ACK] Contact header ~> [<a class="moz-txt-link-rfc2396E" href="sip:11988582770@190.109.68.250:5060"><sip:11988582770@190.109.68.250:5060></a>
