Hi,
recently we switched from CME to CUCM (11.5). Basic telephony services, ITSP sip-trunk etc. are already up and running fine.
However I'm now facing a challenge on configuring the call distribution for our -0 extension. The requirement would be, that inbound calls for extension "0" are signaled like this:
Our two assistants' phones are ringing for 5 seconds (first stage)
The two phones from stage one and three more phones of select employees are ringing for another 5 seconds (second stage)
Mostly all office phones are ringing until the call is dismissed/answered (third stage).
My current implementation in CUCM has:
Three Lingroups (Stage1, Stage2, Stage3) with the phones as described above. The distribution algorithm is set to Broadcast
A Hunt List with the groups from above
A Hunt Pilot pointing to the Hunt List
This setup gets the job done and the phones are ringing as they are supposed to. However there is a major drawback to this implementation. All phones that were ringing are receiving missed calls - although the call got anwered by another phone. I understand that this behaviour is intentional and not a bug so I'm looking for a better solution.
With CME each phone had two lines used: Line1 was the personal Directory Number and Line2 was an overlay of shared lines.
The assitants phone had the overlay with stage1, stage2 and stage3. The select other employees had only stage2 and stage3 in the overlay and the remaining phones only needed stage3 as line2.
Since CUCM does not support the concept of shared lines this setup is not feasable as it would "waste" up to 3 lines on an assistant's phone.
Note: The 2nd and 3rd stage Line Groups can't contain multiple shared lines since the Blastgroup option does not work well with shared lines (at least the CUCM documentation tells me so), thus the need for up to 3 lines.
I'm open to suggestions how to achieve the above described call distribution, without logging missed calls on the user's main Line (Line 1) and not waisting more than one extra line per phone.
thanks,
Fabian

Hi,
so our brand new and shiny BE6KS just arrived, and I'm going to set it up the next couple of days. I already have some lab experience with a CUCM - however in our production environment we are migrating from a UC560.
I went through the available documents, especially the Midmarket BE6000 CVD, the PreConfiguration Guide and the relevant parts of the BE6KSIG setup guides.
What I was missing is a basic overview on how the stock configured BE6KS should be integrated on a LAN. However Andrew Hickman posted some real useful information about this here: https://supportforums.cisco.com/discussion/12450581/typo-be6000s-quick-start-guide
Ciscos take on the appliance is to have it as a small self contained blackbox with a tiny 172.27.199.0/26 subnet. CIMC, ESXi, ISR all listen on this subnet and have the default route out of GE0/0 of the ISR. GE0/1 is, what I would call it an access/maintenance port if you need direct access to this tiny subnet for setup reasons. With this setup I see the BE6KS as a "leaf" in my network - what I personally don't like that much. Especially what I don't like too much about this setup is, that the voice VLAN for your IP-Phones has to go to through a central router to be able to talk to the UC Apps. This might be a bottleneck. Also managment of the ESXi (and possibly VM-Backups) all go out through the shared GE0/0.
So my take on the Setup would be the following (we have DataVLAN1, GuestVLAN2, VoiceVLAN100) :
UCSE-MGMT: Use this port for CIMC and have it connected to our DataVLAN (there is no way to have CIMC bridged to UCSE-GE2 right?)
UCSE-GE2: Use this port in our normal DataVLAN, and have the ESXi-Mgmt connected to this port.
UCSE-GE3: Use this port for the UC-Apps and have it connected to the VoiceVLAN
GE0/0: Use this port for the ISR (config, MGCP) have it connected to the VoiceVLAN
A router, which is already present will route between Data and VoiceVLAN so UC-Configuration, Webservices etc. are reachable from all of our data VLAN.
Yes, that's 4 lan-cables coming out of the box than rather one, but I like to have my things physically structured.
The main advantage is, that UC-Apps and Phones are on the same subnet and on the same vlan. So if our router has performance issues or dies or just has to be rebooted telephony service won't be impaired.
What do you think? Is this a valid approach for a small scale deployment? What could be improved?
Regards,
Fabian

Hi Shashank,
thanks for your reply! So basically if want to upgrade my CUCM to let's say 12.0 sometimes in the future I need all my UWL licenses under SWSS cover to have them migrated to the next major version.
What would happen if I purchase 1 year of SWSS and would like to update to a newer major release in let's say 4 years? Would I buy in 4 years another year of SWSS or would I need to also cover the gap of 2 years?
regards,
Fabian

Hey guys,
since HW support for the UC560 is ending soon we are going to migrate this fall to a BE6000S. I received a quote from our distributor back in February which now got update due to price / USD/EUR exchange-rate changes.
We requested a quote on a BE6000S (4xBRI) with 36 months smartnet hardware support.
Additionally we are going to purchase the 35 UWL license starter bundle. The quote back in February listed those three positions.
However the updated quote now additionally adds 35 SWSS UPGRADES BE6000 UCM v11 CUWL for a period of 12 or 36 months. The price is 2 to 4 times (depending on the period) the price of the UWL starter pack - thus being a significant amount of the quote total. My contact at the distributor was not able to explain what those 35 SWSS UPGRADES are and why they are need. He also could not answer what would happen if we opt for the 12 months? Will the 35 UWL stop working after 12 months or what is going on there?
Maybe someone can clarify the nature of those SWSS UPGRADES and can confirm/explain the hefty price-tag.
regards,
Fabian

Hello, We own several WAP321 which work fine. For our site expansion I now purchased a WAP371 for the dual-band capability. To test it and set it up, I just replaced one WAP321 with the new WAP371. The device came up fine (both radios disabled). I first configured the 5GHz Radio - which worked fine. I chose the lower bandwidth mode, because our SG300-P switch is only PoE not PoE+. I then enabled the 2.4GHz Radio and the AP immediatly rebooted. Once it came back up, it rebooted straight away as soon as the WiFi-Symbol lit up. I reset the device to factory defaults and just enabled the 2.4GHz radio. As soon as teh radio came up the device reboots. It's the same behaviour whether I plug it directly into the switch or use some some RJ45 jack in my office. The SG300 24P port that the WAP371 is plugged into displays an increasing power overload number. As the device is certified for 802.3af I assumed that it would work at least with a single radio configuration. Is it possible that the WAP is defective? - Changing the switch port also didn't help btw. regards, Fabian

Hello, The site https://supportforums.cisco.com/document/36746/uc-500-software-packs lists all supported model/firmware configurations. The 9951 phone is supported since UC500 Software Pack 8.6 which includes a phone load version 9.2.2 Since you are running the latest release you are good to go. If you enable the load within CCA and add the phone to your UC500 network (I needed to add the phone's mac manually within CCA) it should get up/downgraded to 9.2.2 and register with the UC500. However, don't expect too much functionality. 89xx and 99xx phones are only supported via SIP (not SCCP) and are missing most of the nice features. Edit: On a sidenote the UC500 series is EOL and the final hardware-support for the UC500-Series ends in early 2017. Fabian

Hi Andrew, thanks for your swift response. Before going through with the upgrade I want to test our CTI-Integration with the UCM Api. As I understand cisco is issuing 60day-demo-licenses for CUCM which can be installed in a vmware environment. I tried to register a 10.5 license, but I was asked for a code from the Prime Licensing Manager (PLM). Which seems to be the successor of the ELM. After obtaining the license I still need the software iso, which I have no entitlement to download. What is the recommended process (if it exists) to get a demo setup of CUCM for evaluation up and running? How do I get the software? regards, Fabian

Hello, several years ago I deployed a UC560 (with a total 4 BRI ports where 3 are used) setup in our company. It's a small scale setup with about: 30 VOIP endpoints (796x) 3 FAX-machines (on FXS-Ports) 1 FAX-machine attached to an internal (ISDN BRI) We have 2 ISDN trunk lines connected to BRI ports, one remaining BRI is unused. If we decide to go along with the BE6000S I have some questions that I was not able find in datasheets: - I can use the old 7960 and 7962 phone right? - Does the BE6000S device come with FXS ports? Are there VIC-Cards to add FXS ports? - The configuration of call handling Incoming/Outgoing routing, DIDs etc. is this done by a software like CCA for UC560 or is only IOS console commands only? Another important thing I implemented on CME was a click-to-dial function from within our intranet system. I used the cisco JAVA CSTA SDK to remote-dial the phones. How can sth like this achieved with CUCM? I need an interface to CUCM where our webserver can issue a comand dial numbers for specific phones. I don't need to migrate settings or anything. Our deployment is very straight forward and the configuration is very simple. Mailboxes can be erased and will be recreated. Any other thoughts? thanks + bye, Fabian.

OMG! just realized that my telco doesn't send the caller ID! however debug isdn q931 shows, that they submit the call plan type as national... Plan:ISDN, Type:National Using the CCA reginal call plan settings might fix my problem, however I ditched them because of the default access code. I will probaby need some translation rules that take the "type" into account. How do I do this? regards, Fabian

Hi,
our UC560 setup is now running for quite some time. But there is still this one issue that is bugging for some time now.
We have two ISDN DID trunks for Incoming / Outgoing calls.
After my very basic setup I noticed that all caller IDs get their leading zero stripped. In Germany we use the "0" as first digit of the area-code and "00" as the international code.
I thought a quick fix would be to just add a Call-Back Rule within CCA to add a leading 0. This works for national calls as the transmitted caller-id always includes the area-code even for local calls.
However If I receive an international call (what happens quite often recently) I'm not getting the expected "00" in front of the number but also only a single "0".
I took a look at all translation-rules that are configured, but I couldn't find any rule that just deletes all leading zeros from the incoming number :( What's happening there?

Hello, After doing some extensive testing, reading and troubleshooting I found the issue. The deployment guide for the 7925G IP-Phones reccomends to set the lowest transfer rate for the AccessPoint to 11Mbit/s or higher. I did changed the basic-rate to 11Mbit/s and the phone is working as it should. If I did understand correctly the phone will use the lowest available rate to save power. If the rate is too low a transmission queue can build what leads to delayed or not all signaled calls. regards, Fabian

Hello, I recently bought one 7925G WiFi phone. Our setup is a UC560 connected via series 300 PoE switches to our IP-phones. It's a reasonable small deployment counting a total of 25 phones and 25 clients. For the WiFi we are using WAP321s from cisco, also powered and connected through the series 300 switches. My first approach to register the phone was to setup a new voice-ssid on one of the WAP321s. This voice-ssid has the vlan-100 voice tag. I also configured the switch port for tagged vlan 1,2 & 100 (2 ist for guest WiFi). As WiFi security I'm using WPA2 PSK/AES. I configured the Wireless Network on the 7925G phone, it connected and upgraded the firmware to 1.4.1SR1 (UC560 8.6.0). The phone showed up within CCA and I configured the phone as I would do with every other phone. The phone did the soft-reset and showed the lines and everything. I also dialed my fixed extension - and made a test call. All positive. Then I tried to call the 7925G. I heared the ringing sound on my fixed 7965 but the 7925 did not ring, nothing. I took the 7925 and redialed my 7965 - nothing it could not connect. A minute later or so it displayed DHCP timeount and tried to reregister again and again. I only could solve this by powering down the phone and restarting it. It then works great for about a minute or two. After this it cannot be called and it is unable to place calls. If I initiate a call within the first minute the call works great - I tested up to 15 minutes. But as soon as I press "hold" on the fixed phone and the MoH is played on the 7925 the audio gets absolutely choppy, or the connection dies. I also tried pinging the phone. After 1 or 2 minutes the phone does not respond to pings anymore but still presents the green WiFi sign (all bars up). The WiFi is idle - only 2 other clients (smartphones) connected with no traffic at all (according to the WAP321's monitoring function. The phone is located 2m accross the from the WAP321 I googled around, updated the loads to 1.4.5SR1.3 which should solve WiFi issues, but nothing changed. Is my phone defective? Is my setup bogus? What might be the problem? regards, Fabian
