Wow, so many people want to configure kamailio with MS. First of all i think you need to get sip debug between kamailio and MS. Kamilio has module to save sip traces. This way you will get sip debug decrypted.</div>

I can't "receive" anything.<br>
<br>
I have generated the certificates and configured in the tls.cfg of the Kamailio:<br>
<br>
[server:default]<br>
method = TLSv1.2<br>
verify_certificate = no<br>
require_certificate = no<br>
private_key = /etc/letsencrypt/ssl/cert.key<br>
certificate = /etc/letsencrypt/ssl/cert.crt<br>
ca_list = /etc/letsencrypt/ssl/ca.crt<br>
<br>
Within Kamailio itself I have it configured to return a 200 KeepAlive to Teams when it receives an OPTIONS:<br>
<br>
event_route[tm:local-request] {<br>
<br>
if(is_method("OPTIONS") && $ru =~ "<a href="http://pstnhub.microsoft.com" target="_blank">pstnhub.microsoft.com</a>") {<br>
append_hf("Contact: <sip: SBC_DNS :5061;transport=tls>\r\n");<br>
}<br>
xlog("L_INFO", "Sent out tm request: $mb\n");<br>
}<br>
<br>
And I have measured the record_route for this new one:<br>
<br>
record_route_preset(" SBC_DNS :5061;transport=tls", " SBC_IP :5061");<br>
<br>
I have created a dispatcher.list:<br>
<br>
# setid(integer) destination(sip uri) flags (integer, optional), priority(int,opt), attrs (str,optional)<br>
1:1:sip:<a href="http://sip.pstnhub.microsoft.com" target="_blank">sip.pstnhub.microsoft.com</a>;transport=tls 0 3 socket=tls: SBC_IP :5061;ping_from= sip:SBC_DNS<br>
2:1:sip:<a href="http://sip2.pstnhub.microsoft.com" target="_blank">sip2.pstnhub.microsoft.com</a>;transport=tls 0 2 socket=tls: SBC_IP :5061;ping_from=sip: SBC_DNS<br>
3:1:sip:<a href="http://sip3.pstnhub.microsoft.com" target="_blank">sip3.pstnhub.microsoft.com</a>;transport=tls 0 1 socket=tls: SBC_IP :5061;ping_from=sip: SBC_DNS<br>
4:1:sip:<a href="http://sip-all.pstnhub.microsoft.com" target="_blank">sip-all.pstnhub.microsoft.com</a>;transport=tls 0 1 socket=tls: SBC_IP :5061;ping_from=sip: SBC_DNS<br>
<br>
I think that one of the problems is that I do not send the OPTIONS to the Teams well, since it is on their panel, it indicates that the SBC is INACTIVE.<br>
<br>
I don't know if you could help me straighten this out a bit ...<br>
<br>
Thank you so much for everything..<br>
<br>
a greeting</div>
