[cisco-voip] Fw: CUBE SIP to H323 query

[Bill Riley]

Your question was is it needed. You even answered your own question which is why I did a copy paste. 

 

Now let’s take a step back one more time. If your question is do you need DSP resources to make a VOIP to VOIP call using CUBE the answer is no. Do you need an MTP for some supplementary services, yes but it depends on what you are doing and the router will allocate one as needed if it is configured correctly.

Now the next question is do you need DSP’s for this. That answer is no. You can use the software MTP in CUCM which you stated you were going to deploy.  If you want to do it in hardware then yes you can deploy DSP’s in the router and configure the router to use its onboard DSP’s as an MTP. To go even further I thought I read in some other posts that the CUBE router can be configured to use an MTP in software on the router without needing DSP’s. The only reason you would need DSP’s is if you had to transcode from one codec to the other or if you wanted conferencing resources.

Dear Sir, 

This is my first project so frankly i didnt understand what you meant by define your requirements. 

Call hold and transfer will surely be there. So do i need dsp resources ? 

My apologies but i am total new to voip, if you could pls take out some time to clear things for me.

I will be thankful

Correct. Your question was if you needed them or not.  Define your requirements.

 

“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. “

Sir, during my research on netpro, i read that i will be needing MTP to provide supplementary services (call hold/transfer). 

I am really confused

No you don’t “need” them.

Hi all experts. 

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. 

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. 

I am a bit newbie to cisco voip, pls guide me 

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.
