Microsoft Edge changes!

This information is relevant for all companies that are federated with Microsoft.

The federated edge server that supports Instant Messaging and conferencing with external companies will be migrated to Lync Server 2010 on Friday March 18, 2011.

After the server migration, the IP address for the microsoft.com SIP domain will change to 65.55.130.30. External companies who are federated with Microsoft may need to make changes to their infrastructure outlined in Instructions below in order for the federation to continue to function successfully.

The IP address for the microsoft.com SIP domain is changing to 65.55.130.30 on Friday March 18, 2011. Depending on how their infrastructure is configured, they may need to make one of the following changes:

  • Companies configured as direct federations using IP address (not sipfed.microsoft.com) will need to update their configuration to the new IP address.
  • Companies using their firewall(s) to filter by IP address will need to update their Access Control List (ACL) to the new IP address

Note: External companies that are configured as an Enhanced federation and have configured their firewall(s) to Allow All (inbound and outbound) on TCP:5061 according to Microsoft’s recommendations will not need to make any changes. They will experience a brief interruption in their ability to contact Microsoft employees through Lync or Communicator while the A record in DNS is automatically updated to reflect the new IP address.
