Hi All,
I have just upgraded Lync server 2013 to Skype for Business 2015 and now when trying to dial response groups through my UM auto attendant they fail with "The call cannot be transferred, returning to the main menu... The call cannot be transferred, returning to the main menu" and then the phone call cuts out.
Calls to the response groups directly from an internal phone work fine. It's just when trying to call from outside.
Where can i start to troubleshoot this?
Many thanks,
Seb
EDIT:
It seems like it's not able to recognise the extension, if i dial an extension that i know doesnt exist (like 9999) i get the same error in the logs.
If i dial 5052 i get straight through to a person, but if i dial 5050 which is set up as a response group it fails.
EDIT 2:
I have checked that the cert assigned to UM and UMCallRouter has the correct subject name.
I have also checked that refer support is set to none.
