HI Cisco
May i have an advice regarding about CUCM integrate with SIP Gateway? Currently Service Provider want install CUCM for their customer. Its mean their customer phone directory number will register inside CUCM
Outbound Call from customer to PSTN will through CUCM then SIP gateway and for incoming call from PSTN will go to SIP gateway then CUCM . The call flow as per below
Outbound Call
Customer > CUCM > SIP Gateway > PSTN
Inbound Call
Mobile > PSTN > SIP Gateway > CUCM > Customer
Call between Customer - Customer 1 call to Customer 2
Customer 1 > CUCM > SIP Gateway > CUCM > Customer 2
Attach i had draw the diagram for this solution. Appreciate your advice for below question and the solution
1. Can i configure SIP trunk inside CUCM then pointing direct to SIP Gateway? Which is mean no need to configure CUBE
2. When Customer receive a call from PSTN, SIP gateway will be need configure to pointing the call to CUCM is it right?
3. CUCM will use private IP, how can customer reach CUCM? I may need to configure some routing is it?
