Hi, we have a provider that has ip ivr 3.5(3) integrated with ccm 4.1(3). This provider gives helpdesk service using its IVR so he wants to give us the same service. The problem is that we are using CUCM 5.1 and when we call the Route Point on the provider's ccm we catch a cti port and actually an agent respond our call. The problem is that we can not hear the prompt. We tried changing the codec from g729 to g711 but nothing happens.
What else can we do, do you know if there is an incompatibility between the versions?
Thanks in advanced,
