Cisco :: CUCM Feature Ring Like CUCME
May 28, 2012
I've looked in many places but cannot see how or if it is possible to configure a phone, in CUCM to have a feature ring instead of the normal ring.In CUCME you go into the ephone x configuration mode, and assign the DN to the phone with the button xfx command. What this gives you is a slightly different ring tone when a call comes through. If I am not mistaken it is the same ringtone they use on the show "24".Is there a way to do this "feature" with CUCM?

I heard from customers calling into the office stating that they have experienced some issues with our prompts and the extension input, that it is not recognizing their input. Stating sometimes it does not work on their land line but once they call back on their cell phone it works. We in the office all had people from the outside call from a land line to our office to verify the issue but the calls went through. We are thinking that they may be dialing the wrong extensions.Has anyone had any issues with land lines having trouble calling in.I am running cucme connected to a sip trunk.

I'm planning to use 2 3560X (access switch) on two different locations connected over two 2921 routers in small ring. 3560Xs are directly connected via fiber. Each 3560X is conected to its own 2921, and 2921s are connected together with GRE over IPSec. So they are creating ring.I'm planning to use small area 0 in this scenario. There are less then 200 routes in the network. Will 12.2(55) IP Base on 3560X support this scenario or I will need IP Services image? "OSPF for routed access" is still little vague to me, there are only tipical case study scenarios.

My customer wants to replace some Cisco 2912 by new routers, but I can't find a way to add Token ring Network Module on 2951 or 3925 routers with the Cisco configuration tool.Does token ring is still supported on ISR G2 routers?

has anyone here played around with uploading compatible audio files for custom rings and MOH and/or personalized backgrounds for the phones? I was only taught the basics in our CUCM v6.0.1 and am looking to figure out how to get some good music on my phone as well as play around with other "cosmetic" features. The phone I'm testing with is a 7971(color).

I need to setup a layer 2 network consisting of 14 switches interconnected in a ring. Obviously, the design of 14 switches in a ring network is dumb, not here to debate that. Unfortunately, it HAS to be a ring. I've been researching the best way to configure RSTP for this. From everything I've read all I really need to do is configure Primary/Secondary root bridge in the center, and change the Maximum Age field to at least 16 seconds? From what I've read you want a minimum of 3 second buffer + 1 second for each hop due to message age being added by each switch hop?

I am looking for a Best Practices or a few places to pay attention to in the Cisco ESW-520-48P switch I have. My VoIP solution is RingCentral, and while they are Cisco phones, I've been hestitant to setup VLANs etc. the way I am used to. Plus setting up Auto QoS seems different than what I am used to with a 3750 switch.
Right now I've left the Smartports Wizard alone, and none of the ports are configured. There are no VLANs or QoS on the LAN currently.
What I was running into were calls cutting out where one side wouldn't hear the other anymore, but the call would remain connected. However, this has happened in this small 15 person office, when there is only one employee here after hours, talking on the phone. There isn't any heavy network traffic, because I have network monitoring showing me low usage (no streaming music, videos, or anything else).
This switch has a Gb connection to a Linksys SR2024 (the server switch), which is also set at Factory Defaults. I mention that because I recently bypassed the ESW-520-48P, and plugged one phone into that switch and the RingCentral phone worked fine for outside calls.
Is there something besides QoS that I should look at in the ESW-520 switch that might be causing a checkpoint of some sort, or interrupting VoIP traffic that I need to configure or disable?
And are there any Best Practices or scenario guides for this switch? I found the Admin Guide, but it really just explains every option in the GUI for the switch. And it seems all of my CCNA training isn't working with going in and quickly troubleshooting this switch besides knowing that something in it could be hanging it up.

I´ve got a strange problem with the connectivity within a ring topology.There are five switches from the SGE2000 series and one SG200-50.The SG200-50 is the root bridge and RSTP is configured.From the root bridge switch (Switch 5) I can ping Switch 0.But I cannot ping Switch 0 from PC0.
On the other hand I am able to ping all other Switches (1-5) from PC0.In addition to that I can establish a RDP connection from PC0 to Server0.This tells me that there is no general problem with the connection from PC0 to the Switch0.
Right now when I want to configure Switch0 the only way is to connect to Server0 first.But we have to move Server0 and this is why I want to manage Switch0 from PC0 like any other Switch on that network.

We are upgrading from Callmanager 4.0(2a) to new hardware and the latest version. We have Callmanger 4.0(2a) and would like to upgrade to the newest version, at least to CUCM 8. We already have the new hardware that is compatible, smartnets and licenses. After looking at the matrix sheet it appears (there were several different upgrade routes but I could only find documentation for upgradring to 7.1(2) and 7.0(1) from 4.x so I am going with 7.1(2)) should we go:
from 4.0(2a) to 4.3(1)
from 4.3(1) to 7.1(2)
from 7.1(2) to 8.0(1)
this gets us to 8 which we can then upgrade to 8.5 or 8.6
So, we have 4 servers, 2 old (Pub, Sub) and 2 new (Pub, Sub). What is the best plan of attack here:
1) Backup 4.0(2a), then do an inplace upgrade on old hardware from 4.0(2a) to 4.3(1). Then backup 4.3(1) and do another inplace upgrade on the same server to 7.1(2). Then load 7.1(2) on the new hardware and restore backup from 7.1(2) on the old hardware. Then backup and inplace upgrade to 8.0 on the new server?
Or
2) is there any way to not have to "touch" or do an inplace upgrade on the old hardware running 4.0(2a), and just run a backup on it, load 8.5 on the new server and import the data over from the backup?

In the Dual ring network using the token passing method, we have the primary ring and the secondary one where in the normal situation only the primary ring is carrying the token in one direction and when this ring is down the secondary will start into operation and takes the token and rotate in the inverse direction of the primary to reach its destination. Why the secondary ring doesn't continue in the same direction to the destination?

My topology is a physical ring, and I need transfer IPTV signal to all site along the ring.For example:
A (headend)--- B --- C --- D
|______________________|
Note: -----: have spoke-mesh defination
_____: no spoke-mesh defination to prevent loop
So, with MPLS/VPLS I can implement it. With spoke and mesh defination, the traffic can transfer form A to B, C or D as drop-continute action in ring topology (between different VC). Everything is good, FRR can work very fast. But when the topology have a failure link, for example the link between B and C, at that time the traffic will go from A to B then B come back to A and A --- D ---C. This action is so stupid, because it can increase delay, jiiter in network. On the other hand, when the node failure ( B failure), C will loss the IPTV signal, even the link from A--D--C always good.

I have a problem with my Cisco 7961 phones not registering on my CUCM 8.6 install on ESXi 5. Weird because I have Cisco IP communicator phones that register with no problem. You guys know what I can be missing. I have restarted the CUCM and services multiple times. The phone log on my phones say it can't find dhcp and DNS unknown host but my CUCM is configured by IP address. I also attached some screenshots

Looks like I still have an issue with LMS to recognize the IP Phones in UT as IP Phones. SNMP RO on Call Manager is enabled and is green in CM (e.g. topology) - so SNMP get is basically fine. The Phones are recognised as End Devices in UT.
As far as I understand, now if I start a Phone Aquisition, the CUCM is polled by LMS to gather additional information about the phones. So it seems there is a problem with the SNMP polling of the Call manager?

bit of a newbie to this call manager stuff but I was having a bit of a play earlier and for the life of me I can not see an easy way to list which directory numbers are in a particular pickup group. I can see the list of pickup groups and how to assign the directory number to a pickup group but surely there's an easy way to find out which numbers are in a particular pickup group???

I was thinking, is there a way to view a report on the configured numbers within CUCM? E.g. not only extension numbers but hunt pilots and other things such as that? Rather than manually going to each page.

Have a potential customer that is looking at the IE2000 series switch and at the Rockwell Allen Bradley switch
Question is does it support Device Level Ring (DLR) capability. I do not see this specifically mentioned in the Data Sheets but it talks about a
Resilient Ethernet Protocol (REP) and I am wondering if this is the same thing?

In CUCME if you do not configure any translation rules and leave the system mainly at default, when a call is routed to the PSTN the CUCME system sends the true calling party ID which would be a users extension number. Is it correct to assume that a CUCM server based system, when too left at the majority of default (without translation rules or stripping etc) that it will send the true calling ID to the gateway?

I am attempting to send net and IPTV multicast to an Entone STB. This STB has some OTT features such as Vudu that need internet access. The DHCP address that we receive from our ISP strictly sends multicast streams to the STB.The first challenge is allowing DHCP options to pass through to the STB.Then I need to figure out a way to pass both the net and multicast to the STB.
