To add confusion, should you want to do 3-way+ video conferencing with 9971/Cameras you need a minimum PVDM3-128 for that. Google Homogeneous and Heterogeneous video conference. The CME Admin guide has a pretty good section on Video, and it similarly applies to CUCM.

However, you may want to price adding the 64-channel versus upgrading the 16 to a 64 and adding a 32. It'll probably be close in price, but just compare. An alternative would be to just upgrading the 16 to a 128, and that would leave you a free slot for more DSPs in the future.

From your reply I understand that I have a 32 channel DSP on the PVDM3-16U32. If I purchase a PVDM3-64, on top of the existing one, I will have 96 channels. Is that correct? best regards, Abebe On Wed, May 21, 2014 at 10:22 AM, James Buchanan <[email protected]<mailto:[email protected]>> wrote: Hello, They are taking the 16-channel DSP and upgrading it to 32-channels. The number of DSP channels you need depending on how many channels of the PRI you intend to use, plus conferencing and transcoding. This particular VWIC card can do 60 channels as an E1 and 48 channels as a T1. Do you intend to configure two PRIs? If so, you need one DSP channel per T1/E1 channel as a minimum. I would recommend upgrading the 32 channels to a minimum of 96 channels so that you have enough resources for both T1/E1 ports plus transcoding and conferencing. Now, the number of DSP channels also depends on what codec you intend to use. For example G.729 is a high-density codec, meaning that more DSP channels might be required for transcoding. G.729b does not use as many DSP channels. I hope this helps!

C2901-CME-SRST/K9 - 2901 Voice Bundle w/ PVDM3-16,FL-CME-SRST-25, UC License PAK 2. PVDM3-16U32 - PVDM3 16-channel to 32-channel factory upgrade What does the PVDM3-16U32 mean? is it a separate PVDM or license? also if I want to purchase a VWIC3-2MFT-T1/E1, what is the PVDM3 type I have to get? (I dont have the right login credentials to use DSP calculator) best regards, Abebe _______________________________________________ cisco-voip mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/cisco-voip itevomcid
