The problem was when I call the CTI route point DN using the local IP phones the auto attendant answer and played the initial greeetings but when the call was coming from the PSTN the auto attendant did not answer nor play the greeting and when I monitor the the port using Application Reporting I can see that the call was forwaded to the CTI route point and the call was dropped after 4 seconds. I am using call manager 3.1.3a and Cisco Extended Services ver. 2.2(2). Is there anyone who already encounter this problem? Can you tell me what is the possible cause of this and how can I solve the problem.
