Hi
I have a Cluster of 2 cucm server running release 11.5.1
i have a Cisco router 2921 with PRI Connectivity to the PSTN, all calls are fine
But now i need to integrate Skype For Business 2015 with the CUCM for audio calls only ,
i have a Edge Server in my customer site , so i have configure a SIP trunk to the Skype For Business 2015
and success to place a call from the Skype end point to cisco phone and to the PSTN number ,
my problem is that if i try to place a call from cisco phone or frpm the PSTN , the call is failed ,
in the cucm logs i see that the CUCM relase the call for the error " service not available "
but all the configuration in the cucm is fine ,
in the cucm log i don't see that it's initiate an invite to the Edge server , and i don't understand why ,
because it's configured fine ,
attach to the discussion cucm log when i try to place a call to the Skype for Business .
i have configure the cucm according that doc
