Hi Tobivan,


I'll try to answer your questions. I am not aware of all your queries, I am answering whatever I know -


1. What is this ? Why it takes so much DLU quantity ?

SK - Don't have any idea on this. Here's what I found -

IP Secure Telephone Equipment

2. What is this ?

SK - Not Aware


3. What is the difference b/w <3d-party SIP (Basic)> and <3d-party SIP (Advanced)> ?

SK - Difference is in the number of lines supported by the SIP Phone. If it support single line like out 7911 its a basic phone, if it supports 2 or more lines like 7940 its advanced.


4. What is this ? Can you, please, provide the examples ?

SK - These can be any phones running H.323 firmware typically Video Conferencing phones.


5. What is this ?

SK - These are the analog phones connected to VG224.


6. In terms of TelePresence what type device does register on CUCM consuming 6 DLU ?

SK - The telepresence codec and the IP Phone gets registered to the UCM. The IP phone 7970 consumes 5 DLUs, while the Codec/Telepresence endpoint consumes 6 DLUs irrespective of telepresence model. Per unity 11 DLUs would be comsumed.


HTH.
