Hi All,
I am having some difficulty setting up a direct sip connection from Callmanager 8.6 to Exchange 2013 UM and want to know if anyone has encountered this or has a solutions. See below:
I am following the exchange 2010 guide as a starter: http://go.microsoft.com/fwlink/p/?linkId=213007
I have the trunk pointing at the CAS 2013 server (which does the SIP 302 redirection to the mailbox server). The behaviour I am seeing is CUCM sends the INVITE to exchange 2013 CAS and it responds with a 302 and the XXXXX@mailbox-server.fqdn (and port) in the contact info in the header. At this point CUCM doesn't even attempt to contact the mailbox server.
From my troubleshooting it seems to want to handle it as a URI so after creating another trunk to the mailbox server and setting up a remote destination the call makes it to the mailbox server but stripps the caller extension in the INVITE.
Is there anyway in the trunk config to get it to follow the URI redirect (i.e. connect to the FQDN and port given in the header)? Having to make seperate trunks to each mailbox server would result in a lot of trunks.
It seems that if the response was XXXXX@ipaddress in the header from the 302 the redirect would work correctly, but exchange returns XXXXX@fqdn
Thanks in advance
Regards,
Daniel
