Lately, I’ve been asked a lot about how to make a bootable disk for a Cisco Unified Communication Manager installation for a lab or test environment. This is quite easy to do, and the procedure has been repeatedly described in various sources. In my lab I use the method described here: http://htluo.blogspot.com/2010/04/how-to-make-non-bootable-iso-image.html IMPORTANT! This method…

Presence allows a user (watcher) to monitor the real-time status of another user at a directory number or SIP URI from the device of the watcher.

Good afternoon, In my newpost, I want to talk about how to add user avatars (profile photos) for CUPC or Jabber centrally.

This made it easy and quick to…
Good morning! As you know, scripting for UCCX or Cisco IP IVR always requires some pre-recorded wav files. These are all kinds of greetings, instructions for performing certain actions, voice menus, etc. Typically, these wav files are recorded with an external sound editor and then uploaded to the UCCX / IP IVR repository. However, you…
Good evening! The last week I delivered UCCXD 4.0 Cisco course. In the topology, I decided to replace UCCX 8.0 with 9.0.2.

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.

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…
Good afternoon, A few days ago, one of the readers of my blog, Alexander Bakulin, asked me what command is used to synchronize E1 links on Huawei voice gateways.
