Cisco Expressway, collaborative edge and the beauty of SRND v10.0 Because I have been away from the grind stone for a while and have, otherwise, been involved in a lot of non-digital work and hobbies, the introduction of Cisco Collaboration Systems SRND (mid November 2013) had gone somewhat unnoticed to me. Time to pick some of the things in it apart. I would like to spent some time on posting on what Cisco has been…
Read MoreJabber Desk phone video configuration The theory So what will this post be about? Video and desk phone, so video will run through the local client and the voice component will be controlled by the desk phone. So in terms of user experience, this means a call is being set up and established and Jabber will bring Video to the foreground using a pop up window. The mechanism that makes this happen is…
Read MoreCisco Unified Personal Communicator v8.5.4 login issue I just love Presence and CUPC, and I dont care what people say about LYNC or MSOC. We run Presence 8.5.3 in a LAB environment and I encountered an issue where I could not log into my CUPC. At the end, the fix was fairly simple, but some one once told me; “it is the journey that counts!” Basically what I got after I configured CUPS is…
Read MoreUsing SRV records for redundancy and server discovery in Presence, Jabber and CUCM As most of the time, I stumbled across this topic, and I was really thinking about posting something about UCCX again, but things change dont they. Especially when working on tightly scoped, well documented and designed implementation, ;-). I have never really given the possibilities of using SRV records much thought, so most of this post is a bit of research for…
Read MoreCUPS high availability Presence high availability, a feature that is quite easy to enable, so why not use it if you run a multi-node environment. This is a quick post on how to enable it and what it does, based on CUPS version 8.6.4. Cisco Unified Presence supports High Availability at a subcluster level. Both nodes in the subcluster must be running the same version of Cisco Unified Presence 8.x software for High Availability to work. This means that…
Read MoreCisco Unity Connection Call Handlers Call Handlers are a very good way to implement simple call flows. For more complex call flows and IVR’s; CUC is definitely not the place. CUC is the place to set up call flows for extension that require an automated open/closed greeting for instance for reception numbers. This is exactly what I will elaborate on in this post. There are a few steps that will need to be taken in…
Read MoreNumber plan globalisation (based on the Australian Numbering Plan) – Part 2 The Chuck Norris Route Pattern Part II of my E.164 globalization on Cisco Unified Call Manager series. In this part, I will discuss and describe the nuts and bolts of making E.164 happen. In part one I have already discussed the why. Cisco has a really good chapter on this topic in their services and features guide: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/8_5_1/ccmfeat/fscallpn.htmlhttp://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/8_5_1/ccmfeat/fscallpn.html INBOUND CALLING PARTY NORMALIZATION…
Read MoreCUCM restrict caller ID ANI “How to restrict or block a caller ID (ANI) from being sent, in CUCM” Or how to restrict Caller ID presentation” Modification or restriction of ANI (Automatic number Identification, but I will use the term caller ID) is a very common requirement in Telephony deployments. There a heap of ways of modifying the caller ID and on CUCM deployments this is traditionally done through the external phone number mask on…
Read MoreSecure signaling and Media exchange Part I Introduction This first part, of a two part post, I will describe the technology behind secure signalling and media exchange in a Cisco Unified Call Manager deployment. It will describe how secure signalling and media exchange between phones, Call Manager and an H323 gateway, works. In part II, I will describe the configuration steps required to pull all this off. A lot of UC engineers might never come…
Read MoreViewing Core dumps CUCM Core dumps, ah yes! The boring stuff. Some times an unavoidable part of a troubleshooting process. they can be particularly useful if you see certain services restart on your server for no apparent reason. This is a quick little post on how to obtain core dumps and how to capture their output and what to look for once you have the output. What are they? Core dumps occur when a Linux process…
