If your customer has an existing support contract for UCCX, then they would actually order the upgrade via the Product Upgrade Tool (PUT). Is that the case or support has expired? If the latter, then it's likely best to contact a partner as there may be additional items/support that must be purchased. Hailey

First, the route pattern in CUCM simply routes the call to the gateway and passes along the final called number pattern. If your gateway is running MGCP and registered to CUCM, no dial peers on the gateway are used and whatever is sent from CUCM is passed along as the called number as CUCM controls the MGCP gateway. If your gateway is running H323, then you need both. CUCM routes the call to the gateway and sends along the called number pattern. However, the H323 gateway then needs to match that pattern to a dial peer to actually route the call. Technically, it could match a translation rule in IOS and then be passed along to a dial peer as well - point is, the H323 gateway needs routing rules for the call to go anywhere. If you run MGCP but failover to SRST, then your gateway fails over to an H.323 configuration and the same rules apply except CUCM is removed from the picture. Digit analysis and call routing is handled solely by the SRST gateway. Hailey Please rate helpful posts!

You need to look at not only how many users but also the features that are required...you may consider a Business Edition solution as well. In short, the best practice will depend on your solution requirements. Hailey

No problem - I believe their UC service offering is called MaxxPoint...has a lot of features and they've been around a while. They are a Cisco partner and a Gartner leader in UCaaS. Hailey

It's not really a matter of "supporting" MGCP or not...it's a matter of preference. If you're going to use SRST then my preference is to just use H.323 for the remote site gateway. You can do MGCP with failover to SRST and that's OK too. When you do that, you use MGCP and CUCM for standard call control/processing but then fall back to an H.323 config on the same gateway for SRST call processing...hence, that's why I'd say just use H.323 to start with.

My colleague Bill's blog as noted above is worth the read. You will get a mixed bag of answers on here from folks who believe that you should always use H323 to those who only have used MGCP because of it's simplicity when setting it up. To summarize some of Bill's points: If you have a remote site and need SRST, it's usually easier to just use H323 (or SIP) because you're gonna need much of that config anyway to get much value out of SRST. If you are not comfortable with IOS and/or have limited support staff, MGCP has some value. It centralizes the call control and routing whereas H323/SIP push it to the edges. There isn't really a one size fits all answer here. Hailey

You could do either - the premise would be the same. You would use translation pattern(s) that expands 4-digit to 10-digit and those patterns would need to be visible by all of the tenant CSS within the cluster. If you have ranges all over the place when it comes to 4-digit ranges and their expansion to 10-digit, then it might be cumbersome and the site code may be the best option there. Either way the concept is the same. For example: Let's say you have a DID range for a DC site that is 202-555-1XXX then you would add a translation pattern of 1XXX and then prefix 202555 within the translation. If every tenant has access to that pattern then you can now dial 1XXX within the cluster to reach the DC site. Or - let's say you wanted to assign a site code of 100 to the DC site. Then you would add a translation of 100.XXXX, strip pre-dot, and prefix 202555. Again, if every tenant has access to that pattern then you can now dial 100XXXX and reach the DC site. In every scenario, the main thing you need to consider is if (or where) you may introduce and/or run into overlap. Hailey

So you have a multi-tenant dial plan and do 4-digit abbreviated dialing at the tenant (site) level...do you have overlap between the extension ranges at each site? If you do, then you won't be able to effectively implement 4-digit dialing at the cluster wide level. Hailey

On the PSTN gateway (assuming you are running H323 or SIP), then you can use an IOS rule to blacklist calls originating from this number. The other option is to use the Route Next Hop by Calling Party Number feature within CUCM (I believe this was introduced in 8.x) to achieve the same effect. If you search for the feature, you'll find some blog posts and/or tech articles that describe how to use it effectively. Hailey

Essentially you want to implement an abbreviated dialing solution within the cluster. In order to do this effectively, you first need to consider whether or not there is overlap in the 4-digit extension ranges among the various DID and/or private number ranges assigned to the phones across sites. There are also overlap considerations for offnet and/or or inter-office dialing patterns (such as if you use 9 as an offnet code but also have extensions in the 9XXX range, etc.). In any case, you can use translation pattern to expand the 4-digit abbreviated dialing to the 10-digit numbers assigned to the phones. Configuration will vary depending on the existing dial plan structure, overlap considerations, requirements, etc. Hailey

Given that this is an ever evolving product with ongoing bug fixes and enhancements, I would encourage customers to upgrade. However, you definitely need to read up on the major version upgrade process for CWMS - it's definitely a new one. From a system and feature perspective, some enhancements I can think of in 2.0 are: CentOS upgrade for the platform (you don't see it but probably a good thing) 800 and 2000 user systems support for up to 250 users per meeting Added Android mobile device support Windows 8 support Hope this helps.
