I need to know whether the Cisco Call manager V8.0 has been tested/approved on a Siemens HiPath 3000 V8/V9 via IP (H323 or SIPQ). If it has is there a document outlining how it is connected and what protocol was used and what features were tested. I work for Nashua Communications in South Africa and a customer has a call manager which we need to connect to. any help in regards to certification and/or testing would help.
