hi there,
we have our Lync servers running with abc.com as a SIP domain and everything was working fine.
recently we have added xyz.com as an additional SIP domain and assigned new SIP domain to some users.
user1@xyz.com (new user)
user2@xyz.com (new user)
user_old@abc.com (old user)
below are the issues we are facing at the moment, need you guys assistance to correct them.
1. user1 and user2 are unable to perform IM/audio call/sharing each other. (presence unknown too)
2. user1 and user2 can perform IM/calls/sharing etc with user_old, also from user_old to user1 and user2 works fine.
3. meeting invitee send out by user1 or user2 can't be logged in by user_old
4. meeting invitee send out by user_old can be logged in by both user1 and user2.
in short, I feel like the new SIP domain does not work properly, please assist me how can I take it further.
