Hi,

can anyone have a simple and short document to design complete UC platform?

i am more interested in different platform such as CUCM, VCS, WEBEX, CISCO SPARK, CMR, ON PREM WEBEX, INTEGRATION WITH LYNC and so on.

"can anyone have a simple and short document to design complete UC platform?"

Not really.

Designing a complete UC platform is neither simple or short.

I would suggesting bringing in a Consultant or recruit for a UC person with some previous experience managing a large UC platform.

i am more interested in different platform such as CUCM, VCS, WEBEX, CISCO SPARK, CMR, ON PREM WEBEX, INTEGRATION WITH LYNC and so on.

These are all difference functions of a UC system so it really depends on the requirements as to whether you even need them all.

If you let us know why you are asking, we may be able to help.

As the moment your question is like asking if anybody has a short and simple guide on how to build a jet engine.

Hi all,

for one of our client, i need to design the setup as per below requirement: 

Current setup : client is having 3 sites, at all three sites call manager is placed and there is an inter cluster trunk between each other. there are having local PSTN gateway for their local national and international dialing.

Proposed Setup : in place of 3 individual cucm at three different location, we proposed them single call manager hosted on to their own private cloud. They are having more than enough VMs available and live IPs. Uptime of their private cloud is almost 99.99%.

i need to design this setup. so kindly suggest best practice for the same.

i gone through SRND 11.X but cant able to find any relevant design as per my requirement.

i am more concern about the WAN requirement and call control traffic.

This is all laid out in the SRND, however it is a massive doc and all requirements are in different sections. With that being said you mention you have inter cluster trunks between the CUCMs, that would imply you have separate CUCM clusters as oppose to having CUCM subs from single cluster spread between the sites.  When it comes to designing CUCM it comes down to few things: size, latency from remote sites, local failover requirements, administrative (political) control. If you have an environment that can be fit into a single cluster (up to 40,000 devices in marketing terms) and latency from remote phones is below 300 ms round trip then your goal should be to build a single cluster and configure the remote sites as SRST locations (assuming local trunking). As far as WAN requirements besides the obvious adequate bandwidth and latency you need to ensure proper QoS configuration. Call control traffic is very minimal 265 bps for SCCP phone and 538 for SIP assuming no encryption:

Start with Collaboration SRND 11.5 which covers CUCM and some other apps, then for remaining apps you need to find individual design/config guides:

HI Chris,

Thanks for your valuable reply.

the call control traffic you have mentioned is for single call right?

what are the limitation if I host the CUCM on to private cloud other than within premise.

[Chris Deren]

Correct, but keep in mind this all in bps not kbps, so small amount of data.

As to private cloud vs. on-premise outside of ensuring connectivity and adequate latency, bandwidth and QoS there is nothing to worry about.
