    Centralised multisite topology

    Hi, 1. Since you are not going to use the CME.. MGCP will satisfy your requirement.. 2. You dont need to configure T1 PRI.. To connect to the HQ.. configure a T1 CAS and add this gateway on the HQ CUCM as a MGCP gateway.. (HQ CUCM--->HQGW)--------T1 CAS (WAN)--------->(Remote GW----?Ip Phones)
  5. Hi, have you heard about SRST in CUCM?? Its simple as making the phone work without CUCM.. So the Gateway will act as the call processor and the phones will register with the Gateway!! Check for SRST configs on the CCO Site..
  6. Hi Friends, I cleared Cisco GWGK 642-453 just before 2 hours. Thank you for the support..

    Incoming call on FXO port

    Hi, which gateway protocol u r using?? Is't MGCP or H323?? If it is H323 you can us the command "csim start <called number>" to simulate a call from the gateway..

    ISDN PRI issue on 2811

    What is the IOS you are running?? Also can you make sure that the telco has Ascending or Descending is configured on their end.. We need to configure the opposite to Tel-Co. If Tel-Co has Ascending in Channels then we should have Descending.

    PLZ i need an explaination of DID

    In Simple words "DID" Direct Inward Dial. In the PBX cenario, the internal calls will be routed to the extension using 4 digit or 5 digit extensions based on their requirement. The outside callers will reach directly to the end extensions without calling the main line number and then diverted to the extensions. The complete E164 number used to reach the extension directly is known as Direct Inward Dial (DID) number.
