[SR-Users] Re: Kamailio - Ms Teams direct Routing - dispatcher issues | FLAGS: IP

Here's my last and best trick, which eliminates Kamailio entirely from being the culprit: *sipexer -options -contact-uri "sip:customers.teamsphone.net:5061;transport=tls" -fd "customers.teamsphone.net <http://customers.teamsphone.net>" -td "sip.pstnhub.microsoft.com <http://sip.pstnhub.microsoft.com>;transport=tls" \-tls-insecure -tls-certificate "/usr/local/etc/kamailio/bundle.crt" -tls-key "/usr/local/etc/kamailio/privkey.pem" \-xh "Max-Forwards: 70" -ua "Ribbon-SIPGateway" "sip:sip.pstnhub.microsoft.com:5061;transport=tls"* If you don't get a reply from Microsoft.PSTNHub then something is awkwardly wrong in your setup, not related to Kamailio, likely Teams backend config or networking. Note: (1) adjust certs path to your case (2) install sipexer if you don't have it: https://github.com/miconda/sipexer Regards, Sergiu -- *Teams PBX connector with full MS Direct Routing automation for service providers**Web*: https://teamsphone.net On Mon, Dec 18, 2023 at 3:23 PM faisal.jamil.khan--- via sr-users < sr-users(a)lists.kamailio.org&gt; wrote:
