Here's what I have in my notes on QOS BW calculations. I also included
a formula for LFI when using FRF.12.....
The bandwidth is calculated as follows for Frame Relay:
L2 overhead= 11 bytes
IP/UDP/RTP= 2 bytes
G729= 20 bytes
Total= 33 bytes per packet
bits per packet= 8
50 packets per second
so 33 X 8 X 50 = 13.2kbps (round up to 14Kbps per call)
________________________________________________________________________
__________________________________________________________________
LFI Calculation:
When using FRF.12 ("auto qos voip" or "auto qos voip trust") you will
need to calculate the actual fragment size in Bytes using the following
formula:
Fragment size=(PVC Link speed X 10ms) divided by 8
Example (56k X 10) divided by 8 = 70 Bytes

As a suggestion I would check for the overheads sizing at page 33 of QoS
SRND and for the formulas I would check UCM7 SRND page 134

Subject: [OSL | CCIE_Voice] Service URLs
Message-ID:
<aanlktimxaxxwa6e2-sts2h3sd+gzrpytu0mimemu5...@mail.gmail.com>
Content-Type: text/plain; charset=ISO-8859-1
All,
I've been trying to improve my speed in general... but specifically in
looking up things that I might need in the lab exam. This evening,
I've been working on reviewing where to find all the Service URLs.
Most are too cryptic to memorize. So... assuming you don't have these
memorized, where would you go to look up the following service URLs
during the exam? BTW, I have my answers, but want to see what others
say to compare with where I found these. Maybe you know of a quicker
way to look up one or more of these.
1) Extension Mobility
2) IPMA (IP Manager Assistant)
3) IPPA (IP Phone Agent)
4) IPPA - One touch login
5) IPPM (IP Phone Messenger
6) VoiceView Express (CUE)
Secondary question: Am I missing any? Are there any other IP Phone
Services that would be fair game in the lab exam? The only other one I
can think of off hand is the VoiceView for CUC, but that requires
another server. Does anyone think it could be considered a testable
topic?

Hello,
I got the error "Online install/download is not allowed due to
insufficient
FLASH capacity" when attempting to update the CUE license file. I tried
to
do a software reinstall via bootflash, thinking that it would clear the
flash, but the error still remained.
Can anyone advise what else can be done in this case?
Thanks,
-Dave

Hi Brian,
these are the quickest methods to get those URLs that I am aware of. I
can't
check the locations exactly now, as I'm not in the lab, but you should
be
able to find them:
1) Extension Mobility
CUCM Help > search for "extension mobility checklist"
2) IPMA (IP Manager Assistant)
CUCM Help > search for "ipma checklist"
3) IPPA (IP Phone Agent)
cisco.com > UCCX support page > configuration examples > IPPA one-button
login
4) IPPA - One touch login
cisco.com > UCCX support page > configuration examples > IPPA one-button
login
5) IPPM (IP Phone Messenger)
SRND (search PDF for IPPM)
6) VoiceView Express (CUE)
go to CLI and run "show voicemail voiceview" (or similar) or go to GUI >
Voiceview configuration page (URLs are listed there)

Can someone please tell me why my SIP phones keep registering and
unregistering themselves every 10-20 seconds
??
