Can LYNC 2013 Federation enables to work across the domain

Hi Folks,

While deploying LYNC 2013 in my org, i have been asked by my management that when Domains are trusted with each other so we can even windows logged in at premises of domain trusted organization...

So if lync of two organizations are federated then can one person of Org-A can sign in their lync client with their same credentials while sitting in Org-B?

If yes then how and if no then reason? also federated lync involves edge server so is there any involvment of DCs which domain is two way trusted with other org DCs.

there are two ways in which a user sitting on the Org-B network could sign in
If the domain is trusted and internal DNS is functional then they would be able to sign into the normal Lync client as an internal user i.e. if they can resolve sip_internaltls.domain.internal and reach all the resources

or they would sign in as an external client which would mean they would need internet access from org-b to be able to get to edge servers

these two scenarios are separate from Lync federation. Lync federation mean that Lync users from org-a are able to see presence, im, video call etc usres from org-b and vice versa. this is done by Lync edge services and does not involve the DC's from each domain talking to each other.
