Hey All
Weird one and my google-fu has failed. We have an over complicated environment with multiple sip domains, a mix of 2010/2013
pools on prem and an Office 365 tenant. Our 365 users are federated with our on prem domains, and, they are firewalled etc from our networks so everything has to flow to the internet. We share an Exchange 2010 environment so full GAL lookups etc.
Here is the weird part. I'm homed to the on prem pools; either one, doesn't matter. I log in with a 2010 client and I can search
but can't find our federated partners with full sip address, I get a hit in the address book to a phone contact that is published in Exchange/AD (we don't use enterprise voice). If I log out of the 2010 client and log into a 2013 or Skype4B client, I can lookup
the federated user by full sip and then start any conversation I want, IM, video, audio, etc. It's just the 2010 client that seems to be indignant, my homed pool does not matter. So what is the 2013 client doing to find the federated partner that the 2010
client is not. I checked Tools>options and they appear to be the same. Does anyone know the difference in how the subscribe works between the clients or am I looking at a DNS issue or.....? It's got me stumped.
