Hello Rhys,

thanks. About the presence integration question - according to my research currently the only possibility would be to use the existing Skype APIs and then use this (per interop-mode) also in MS Teams.

Microsoft announced the availability of a API to set the presence status also for Teams, this is now scheduled for Q1 2020. There are other limitations which also needs to be solved from MS and they are also scheduled for Q1 2020.

Feel free to contact me directly if you are interested in this topics.

Cheers,

Henning

Hi Henning,

This is a great article, thanks for sharing. I'm wondering if you've experimented with the possibility of integration of presence/dialog information with teams as well?

Pretty much every integration guide I've seen on MS's UC solutions, including the previous ones (Lync, Communicator, SFB ) always seem limited to integrating calling via trunks. To me, the integration is not complete unless you can integrate presence things like:

* If a user is on the phone then their status should be "busy" on Teams. When off call, set back to Available. * If a user is on a call in teams, our PBX should consider their PBX extension as "in use".

Not sure it's possible, because I haven't seen anything of the sort being done yet, but I'm curious if this is something you looked into at all?

Thanks. Rhys.

nice to see that howto. Thanks.

Maybe interesting for the list - i try to verify the ms-teams calls with tls and use the permission module functions as "helper":

# account only INVITEs if (is_method("INVITE")) { setflag(FLT_ACC); # do accounting

xlog("L_INFO", "-----------> tls_peer_subject <$tls_peer_subject> tls_peer_subject_cn <$tls_peer_subject_cn> tls_peer_verified <$tls_peer_verified> tls_peer_server_name <$tls_peer_server_name> \n"); xlog("L_INFO", "-----------> $Ri:$Rp src_user=$fU src_domain=$fd src_ip=$si dst_ouser=$tU dst_user=$rU dst_domain=$rd\n");

if($tls_peer_verified == -1) { xlog("L_INFO", "tls_peer_subject_cn $tls_peer_subject_cn is NOT verfied!\n"); return; } $var(dns) = $tls_peer_subject_cn; $var(group) = allow_address_group($var(dns), $Rp); xlog("L_INFO", "-----------> allow_address_group var(group) $var(group) var(dns) $var(dns) Rp $Rp\n"); if ($var(group) == -1) { xlog("L_INFO", "Trunk is not activate for registrar DNS_GROUP:[$var(dns)], Source: [$si], Destination: [$Ri] Port:[$Rp]\n"); return; } }

Hi, I think it's not needed/able to get kamailio listed as certified SBC by Microsoft because the configuration is raw and flexible. The `How-to` is just about the SIP stuffs fulfilling Microsoft's requirements for the connectivity. Your request should be valid with some GUI project that wrapping the kamailio, not with the kamailio itself.

Hello Stefan,

it is certainly possible to get a certification for an open source software (server). Usually the work that needs to be done is related to documentation, testing and probably some packaging.

So far I did not looked into it that much. I think it is probably something that is more interesting from a commercial point of view and not in an open source project context.

Cheers,

Henning
