[SR-Users] Kamailio as SBC for Microsoft Teams

[Henning Westerholt]

Hello,

I have created a "How-To" blog post on using Kamailio as "session border 
controller" for Microsoft Teams Direct Routing:

https://skalatan.de/de/blog/kamailio-sbc-teams

You can this way use all the existing possibilities that Kamailio provide to 
interact with MS Teams as well.

Best regards,

Henning

Hello,

thanks for sharing! This can be added as a news article on kamailio.org,
over the time can be found easier there than in the mailing list archive...

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.

[Henning Westerholt]

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,

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)

if ($var(group) == -1) {
xlog("L_INFO", "Trunk is not activate for registrar
DNS_GROUP:[$var(dns)], Source: [$si], Destination: [$Ri] Port:[$Rp]\n");

Hi list

Sorry for coming back to this older thread.
First: Thank you Henning for your blog post.

Does anyone know what is needed to get Kamailio listed on the certified 
SBC's at microsoft?

Is there already a plan to get Kamailio on this list?

Thank you and regards

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.

[Julien Chavanton]

Hi, I know they have a few customisations to SIP and RTP.

Nothing  concerning from what I know.

One example the SDP RTCP address, I do not have the RFC on top of my head.

But the certification is probably only needed for them yo list you as a
certified equipment, etc.

Re: [SR-Users] Kamailio as SBC for Microsoft Teams

[Henning Westerholt]

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
