CUCM Skype For Business not working

[Maheer Brown]

Hi Guys

I'm struggling to get Skype for Business 2015 working with CUCM 10.5

I followed this exact config guide but I keep getting "your organization does not support calling this number" error on the skype client when trying to dial out.

Please help?

Thanks

From RTMT, can you please share real time trace for failed call.

Also, where are you getting this error message from CUCM or S4B?

Salaam Mohammed

See trace attached

The number (0723779056) is being dialed and not showing in the trace

CUCM IP: 10.1.10.40

SFB IP: 10.1.200.64

Error message is coming from the SFB when trying to dial.

Also I cant see the Cisco phone attempting to dial the number as well

Thanks

ok this look interesting. Do you have route pattern configured and pointing to s4b sip trunk.

use DNA to trace the called number from cucm and see where its getting lost.

Also, what is you calling phone?

[Maheer Brown]

Yes route pattern with the gw set to the Skype trunk

Using a softphone for testing purposes

[Mohammed al Baqari]

Good. So configuration looks good. Now I don't need sdl trace. From RTMT navigate to real time trace and share the ladder diagram for the call.

Make sure that you have select 60 mins as duration then search for the call. I need to see the SIP message involved in the call.

[Maheer Brown]

I cant see any detail

So basically when dialing from SFB then the call doesnt even hit the CUCM

[Mohammed al Baqari]

Can you hit cucm from the machine running the softphone?

Did you add the softphone in cucm? What softphone are you using?

[Maheer Brown]

If I dial from the Cisco softphone then everything works 100%

When I dial from SFB then nothing happens

Basically trying to configure the "click to call" 

[Nadeem Ahmed]

Can you pull logs from OCS logger from SFB to see what exactly its happening around.

[Mohammed al Baqari]

Then its S4B problem. I suggest you post this in MS forums to and see if they can help. Unless the message hits CUCM nothing can be checked from CUCM side

[Nadeem Ahmed]

Did pulled the logs from OCS logger its quite easy to see and understand message from OCS tool and help you figure out where the problem persist and accordingly take appropriate action
