Just want to mention that "standby use-bia" solves the problem for the CSRs running in GNS3!

Yes, that's fine. I was planning to use Cisco ASA as a firewall, behind the routers. Does that make sense?

Hello,
I'm working on a project where we have to replace one BlackDiamond 10808 switch and NetScreen ISG1000 firewall. As you can imagine these are pretty old devices although they are solid and still working. So, we decided to look into Cisco as an Enterprise soltuion. The requirements that should be met are:
- Gigabit interfaces and firewall throughput (scalable to 10 G - optional)
- BGP with independent AS
- HA with possible second pair of devices in another datacenter
I have experience with Cisco's ISR routers but I think that a better solution in this case will be some ASR router probably. Also, the switchports from the BD switch are not part of the current scope. I'm looking for the routing agregation and the firewalling at the moment.
Please for your advise and thanks in advance!

It makes sense so that the others will not try useless things. When I wrote the commend, I didn't have the answer as well.
Regarding the problem itself - recently I was fighting with UC560 and Telstra SIP trunk. As it was explained already, they require globally configured outbound-proxy, otherwise the trunk is not registering and the inbound calls are failing. Even if you put " no voice-class sip outbound-proxy " on some dial-peer, this will not disable it. For example, I had to enable the presence feature between two sites and all the SUBSCRIBE requests are still going to the proxy. It turns out the problem is probably related to a bug in the older IOS versions: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCux20973

I don't think so. It is pretty tough to push even changes as you need to have alternative TFTP configured.
The VPN session is establishing after the phone boots up while the firmware upgrade is happening before that - this is specifically valid for 79xx phones. The new ones are keeping 2 images and they are downloading them while they are up so probably you can upgrade 8841 for example over SSL VPN.

Yep, reimporting the tomcat cert (pem) from the server that you cannot connect to did the trick.

The problem is that the security libraries in 8.x and 10.5.2+ are incompatible. This is why you cannot consolidate the certificates by using the older version. However, you can consolidate them through the new cluster but then you will not be able to import the BULK store back to the old version.

For CentOS 6.7 and RTMT 10.5, except the libraries mentioned above I had to install libXrenderer.

For the screen recording there is a thin client that should be installed on the desktops (Windows only). It will connect to the server and will wait for a call in order to start capturing. It is a background process and it is completely silent for the users.
Regarding the on-demand recording - there is no such feature at the moment. There is something called "Prerecording" which is recording everything by default and will keep it for few minutes. Then there is a XML app that you can run on the phone to choose what to keep.

If the call is missing in the Web UI, then the problem is in the JTAPI. First of all, do you see these records there and do they appear as "no streams recorded" calls?

There is a workaround for Firefox and Chrome. Check this out - http://www.learncisco.net/blog/security/server-has-a-weak-ephemeral-diffie-hellman-public-key.html
