I will be using CUCM v8 and connecting it to 2821 (running CME or higher) over H.323. SIP trunk will be terminated on this 2821 router via local ITSP. <br><br>After researching alot on cisco, kindly guide me that do i need DSP resources for translating between SIP and H.323 ? My findings were. If i want to support supplementary services then yes i need DSP. For basic calls, i dont need them. <br><br>I am a bit newbie to cisco voip, pls guide me <br><br>Note: I know already that instead of H.323 i can use SIP which is more prefered. But still to clear my concept, guide me with respect to H.323 trunk between cucm and cube.<br></div>
