<meta http-equiv="x-dns-prefetch-control" content="off">The supplementary services that you're referring to that require DSPs on CUBE are not the traditional 'supplementary services' that are normally talked about. The supplementary services that require DSPs on CUBE are things like volume normalization, echo cancellation, and some frequency smoothing techniques. I don't believe these are all that commonly used, but they are still pretty cool and powerful features.<br>
<br>In order to support hold/transfer/conference and the normal "supplementary features" you should NOT need an MTP for a SIP trunk. Normally when you enable an MTP to get these things to work it's a band-aid for another problem or a misconfiguration. MTPs are very good at fixing those types of problems, but you should not need an MTP. Now, for H.323-SIP you may end up needing them as the requirements for that are a little different than the standard SIP-SIP.<br>

all experts. <br><br>My scenario is simple. 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.</p>
