CCM 6 + CUPS + OCS 2007 integration notes:

I would like to summarize the integration notes for the above configuration, kindly find below the latest notes for OCS/CUP integration:

1. To have CCM/OCS integration you will need to have a SIP trunk between the Mediation server GW facing NIC and the CCM, otherwise it will not work (calls will get service unavailable errors).
2. To have Voice-mail auto redirection (a phone missed called redirected directly to the extension’s Voice mail) you will have to enable caller-ID on the SIP trunk, otherwise the user will get an auto-attendant.
3. For Auto-attendant feature in Exchange, just create a new auto-attendant as voice enabled, assign an extension and create an Extension routing rule on the CCM to redirect the call to the Exchange feature and it will work.
4. To do presence integration you will need CUPS in-place, we didn’t have the time to test that.
5. Feature that has been tested successfully:

• PC to phone calls
• Phone to PC calls.
• Dual forking (from calls coming from OC).
• Multi-group conferencing (OC – Phone – phone).
• Voice mail and missed call notification.
• Call forwarding to phone, PC and VM.
• OVA
