Firmware Upgrade for Cisco IP Phones (CUCM)

Good morning!

I wanted to write this post long ago, however I was extremely busy and did not get around to take the required screenshots. And when preparing for the next course, I had to upgrade the firmware on our lab phones. So it became possible to write about what needs to be done on CUCM to update / change firmware. The procedure is quite simple.

CUCM 9.0 - How to install licenses

Hello!

Today we'll talk about how licenses for CUCM 9.0 are installed. Since the process in the new version differs significantly from earlier predecessors, I will give the entire installation procedure with screenshots taken from our lab CUCM.

CUCM 9.0 - Pause when dialing a number with the Speed Dials keys.

Good morning!

The festive New Year's fireworks have died down, and working days are coming again. :) I decided to start 2013 with a small article devoted to the problem of inserting a pause in extension dialing when calling from CUCM to, for example, your PSTN.

Quite often, on various forums, the question was discussed - how to implement automatic extension dialing on CUCM? Suppose a CUCM user calls a company where not all employees have direct incoming DID numbers. Instead, the call arrives at the company's general number, and then the auto-attendant or DISA function is triggered and prompts you to dial the employee's extension in DTMF mode. In manual dialing, this can be done without problems, but what about the speed dial buttons on Cisco IP phones? How to pause for them while playing the auto-attendant greeting or, in the simplest case, while establishing a connection with the called PBX?
