our Costumer need a solution for Call Manager Integration with MS Lync. He has a CUCM with hard Phones, Presence Server and a Microsoft lync. The Call Manager is connected over SIP to the MS Lync Server.
So the Costumer dont want the RCC Solution and has no LDAP Integration. His wish is if someone calls on the Cisco Phone the Status at the Lync Client should be on Busy. If u are on a call with the Lync Client the phone should be Busy. This have to work from everywhere, that means if the Costumer is at home and work with a private computer and uses the Lync to place calls then the phone at the Office should be busy.
Have someone a solution for that. Thank you in advance.
