Skype for Business vs Jabber + Expressway

[steigja]

Hello All,

     I'am trying to figure out a comparison between Skype for Business and Jabber with Expressway.  How does Skype for Business work when you are outside of the organization similar to how Jabber would work with expressway?  Is there any good documentation on a comparison.  I know that CUCM can integrate with Skype for Business server through a SIP trunk.  Thanks

Obviously not a MS guy, but from what I know they use DAS as the equivalent of MRA

MS has pretty much same concept of Expressway-C and Edge. You need a Microsoft edge server to achieve this.
