Good Morning,
at the Moment our Workaround consists of changing the IE Option to sslv3 when working with CUCM and changing it back to tls when we've finished. Not very satisfying. I'm waiting for the test results from Mase4g638 concerning the SHA2 cert.

Ha ha, TAC is making jokes. The only IE version which is officially supported for Windows 7 since beginning of this year is IE11!!
This statement is synonymous with "Don't use Windows 7 to administrate CUCM" or "Buy a newer Windows Version to administrate CUCM".
Of course you can install an older Version but you get no more security updates and some homepages don't work if you have installed an older IE version.

We also have other servers with web front-Ends and SHA1 certificates, which are working as usual. The little difference is, that these certificates are all 1024-bit signed.
The CUCM SHA1 certificate is 2048-bit signed. I don't know what "feature" Microsoft has build in their IEs with the last updates to generate this behavior.

This Workaround is working for us, too.
Nevertheless I think, Cisco should illustrate a solution to recreate the selfsigned CUCM certificate as SHA2 certificate. This would be a real solution.

Adding CUCM web page to compatibility view has worked till the latest microsoft updates has been applied last week. Since then, it's not possible to use the CUCM web gui any more. "The page cannot be displayed" is shown. We are using Windows 7 with IE 11.
We think it has to do with the CUCM certificate which is SHA1 (SHA-128) coded and the browser which is blocking old certificates.
Is there a possibility to recreate the CUCM certificate as SHA2 (SHA-256)?

Hello Aaron, thanks for this detailed answer and explanation, but I've one question concerning your conclusions. Isn't it counterproductive setting the AP powerlevel to 1 (17 dbm here in Europe)? As far as I know the 792x phone have a maximum transmit power (in -E domain) of 16 dbm. Greetings Frank

Hello Martin, Unfortunately our TAC case was closed, because at one point last year, we were not been able and willing to produce even more and more logs and debugs an invest more and more time without getting any result. At the moment we are considering to replace the whole VoWlan infrastructure, or to try one last step in co-operation with an big Cisco distributor here in Germany. Greetings Frank

Hello George, we noticed the same issue here in our VoWLan deployment, consisting of an 4402-50 WLC with firmware 7.0.98.0 and 7925G handsets with firmware 1.4.1. Greetings Frank

Hello folks, there's a new phone firmware 1.4.1 available at the Cisco Homepage. According to the release notes, they didn't solve the bugs mentioned in this thread. I will download and test it anyway...... Greetings Frank

Hello Dominic, thanks for your detailed response. I will talk to my distributor, if the new firmware is interesting for us or if we wait for the next official release. By the way, as you seem to have a really "hot" connection to Cisco, have you got any news, when they plan to release a new official firmware for WLC, or even more important, for the 7925? Greetings Frank

Hello Dominic, I've just read in the forum, that a new 7.x code called 7.0.98.205 (an Engineering Special build) is available through TAC. I was wondering if you have already updated your WLC or if your are going to update the next time. Because according to the release notes (you find them in the "Other Wireless" section of the forum) they have fixed one of the three bugs (CSCtg74904) you have posted a few weeks ago, after the visit of the cisco engineer. Greetings Frank

Hello Nicolas, thanks for your quick response. Regarding the diagram of your link, one can see, that the beam (mainly look like an lying eight) is mainly radiating left and right. Is it possible to let the beam radiate from back to front with only changing/turning/artuculating the antennas in another way? Greetings Frank

Hello, in our deployment we have mainly the LAP1252agn with both Radio modules installed and the AIR-ANT5135DW-R 3.5dbi dipole antennas for 5 Ghz and the corresponding 2.2dbi dipole antennas for 2.4 Ghz. According to the Cisco antennas reference guide one can say, that the elevation plane radiation pattern looks a bit like an eight. At the moment the antennas on the access points are deployed as seen in figure a) of my attached draft. My question is, whether it is possible to turn only the antennes in a specific way, so that the direction of the beam can be changed as seen in figure b). Or do I have to turn the whole access point as shown in figure c) or to mount it on the ceiling as shown in figure d). Thanks. Greetings Frank
