Hi all, the latest release of Cisco Call Manager is Version 4.0 and it is supposed to support SIP: http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_data_sheet091… Has anyone already tried whether Cisco's implementation on Call Manager is compatible with the Sip Express Router? I want to connect Call Manager controlled in-house networks to a ser-based system with Cisco 2611XM as PSTN gatways. Any ideas whether this will work?
