Skype and Microsoft - What to expect when the streams cross?

May 10, 2011

Being close partners with both Skype and Microsoft, I’ve been living in a dual UC environment for over two years, using Microsoft Lync and Skype at the same time.  Depending on who I needed to communicate with, I had to choose either the Lync or Skype client to initiate the conversation.  Frequently swapping from one client to the other between conversations (fortunately, I can use the same headset). Things get real interesting when I need to pull in both Skype and other non-Skype capable co-workers into the same conversation.  

FAQ: SIP Trunking and Unified Communications - What is the role of an Enterprise SBC?

An E-SBC plays a number of important roles when integrating SIP Trunking service providers to SIP-based Unified Communications systems - including Microsoft Lync, Avaya Aura, IBM SUT and others:

1.            Interoperability – using the Back-to-Back User Agent (B2BUA) features of an E-SBC, they can solve many of the interoperability issues that exists between systems today.  In this role, each SIP session is terminated and re-established on the other side, allowing format difference between the two systems to be corrected.
