Problem Video Call from SfB (office 365) to CMS

Hi,

I have configured CMS to communicate with SfB Office 365 by using Direct Lync Federation method. I use 2 interfaces in CMS, 1 interface uses IP local, connect to CUCM via SIP trunk, 1 interface uses IP public to accommodate SfB federation.

My scenario is, Jabber and SfB meet in CMS meeting room. When I test it, SfB client will always freeze, around 1 minute after conference. But the audio still works. (SfB is only freeze from receiving video, but it's still receiving the audio). From Jabber client perspective, there is no problem during the conference. It still receive the video and audio from CMS.

Has anyone experience this issue?

Hi Ferdi0802

Hi

Is your call bridge configured with the public IP or are you using a Nat and Turn services?

Hello Ferdi0802,

Hello Ferdi0802,

If you could help, apart from DNS SRV  as described in doc:

Discover destination for calls to third party Microsoft infrastructure domain
(Outside of your control, but needs to bethere for federation to succeed)
SRV _sipfederationtls._tcp.msexample.com 5061 Public address of Microsoft Skype for Business Edge server

is there something else to be done on the MS "federated to be" domain ?

Thanks.
