Using SQL to clean up Call Manager pt2

See Part1: http://longoconsulting.eoreality.com/wp/2017/04/29/using-sql-to-clean-up-cisco-call-manager/

Previously we had around 700 dependencies on a CSS that no longer fits our standard. This CSS was in use by lines, devices, and users throughout the system. In part 1 we removed this css from the users, now we need to do the same for the devices.

Using SQL to clean up Call Manager pt1

So, at a client of mine that we will call PRO, we had a Device-CSS which seemed to be the default css for pretty much everything, including presence subscription, even though PRO-Subscribe-CSS exists. Well the PRO-Device-css also used a lot of legacy stuff from the PRI days. I wanted to clean it up and swap things to follow the standards we had implemented, which required naming based on the line of business, location, and use.

First I modified all the templates to remove the PRO-Device-CSS usage and replace it with the appropriate css.
Next I check dependencies, assuming there couldn’t be that many things…

Asterisk integrations with Cisco UCM – MWI

I simply forgot MWI wasn’t working since I get an email and just delete the message via email after listening! My daughter asked me why she never knows if she has a voicemail (she doesnt have usable email) and it prompted me to fix it. I’ll post what I did and how I did it shortly. Since call manager doesn’t inherently support authenticated sip trunks of course, no google voice integration, i’ve used my Asterisk server (running since 2002) as my Gateway for sometime. When I got my hands on a few 88xx, 8945s, and a dx650, I decided to setup call manager. To keep everything smooth, I just send everything to Asterisk and let it route to the cloud. Asterisk also provides my voicemail capability for the asterisk phones (my parents, a few military friends, and a few friends who would like to call locally within the US) and the Cisco phones. Calling into voicemail and diverting calls to voicemail is extremely basic so I won’t discuss this at all, but MWI stumped me. Asterisk handles MWI pretty differently from Unity Connection and I struggled with it for a bit. After an hour of internal server errors I decided to try scripting.

Prior to the scripting, I went ahead and created my MWI off and on DNs, 191# and 192# respectively. Dialing this from my Cisco phones would turn on or off the MWI successfully. So my thinking was, alright, a call comes in to asterisk, routes to cisco whereupon the timeout is hit or i decline the call. this sends a sip message back to asterisk which i use to send the call to the busy or unavailable voicemail recording. I needed to launch a script any time I dialed into voicemail or someone left me a voicemail. After some digging through my asterisk book and the subsequent verification that the options still exist in Asterisk 13, i stumbled upon externnotify for voicemail.conf. This let’s you specify a script to launch anytime voicemail is accessed.

CUCM Licensed Users (9.x+) using SQL

A client was facing some licensing issues with shared devices. After a discussion, we decided to create a local user account for this particular location. Using this local user account, we would assign all generic shared devices (waiting room, lobby, hallway) to this user and save a bunch of enhanced licenses by properly utilizing CUWLs.

I provided some guidance and a local admin began the process of clicking a phone, setting the user, saving and picking the next. Obviously this is pretty painful and slow. I decided to see what we could do to speed the process up.
