Customer: University

University have a Cisco IP telephony estate and wanted to leverage their investment in Office 365 for voicemail services using Exchange Online. As direct connectivity between Cisco and Exchange Online is not supported, I deployed two Sonus Session Border Controllers with failover routing in between Cisco and Exchange Online.

Skills

• Sonus Session Border Controller installation
• Sonus Session Border Controller configuration including SIP, TLS, Transformation Rules
• Integration with Cisco CUCM for voicemail
• Exchange Online UM configuration
