We had this one case open for like a month, and I decided to take a crack at it a few weeks ago. I thought it was a pretty funny issue, that I don’t see too often.

So there was this one user, that kept getting missed calls like 5-10 times a day. And they were always showing to be coming from the Unity server (based on the Caller ID). This was pretty annoying for sure and it was only one user that kept getting these phantom calls.

I’m thinking to myself, when does Unity call anyone? Unity can do message notification right? We get a new Voice mail and we can have Unity page, email or call us. I figured this was probably a good place to start, looking at notifications in Unity.

This first thing I’m thinking is there is no way I’m going through every subscriber and checking their notifications. I knew I wanted to be able to search subscriber notifications and see if any were set to dial her extension (let’s say her extension was 5125).

I opened the Tools depot and used the “Subscriber Information Dump”. You can basically use this tool to write all the subscriber properties to a CSV file and be able to search through them easily. I searched through and didn’t find anything that exactly matched her extension (5125).

I ran this during the day and didn’t affect the system, just make sure to monitor task manager when doing these things. You can also check the “call viewer” to make sure there aren’t a lot of calls to the system.

See below for Subscriber Information Dump location ::

I had a nice one-way audio issue I was troubleshooting on Friday.

Here’s the setup ::

Cali HQ site <-----> MPLS Cloud <-------> LA Regional office (PRI located here for LA Sales Office PSTN access)

Cali HQ site <-----> MPLS Cloud <-------> LA Sales office

This is a pretty simple setup where you have the HQ site with Call manager which connects to the MPLS cloud. And you have the Remote Regional and Sales office that also connect to the same MPLS cloud.

The issue was regarding the LA Sales office which was reporting one-way audio issues for outside (PSTN) and on-net calls (across WAN).

I was at work today and mentioned I was going to be working on the Voice track rather quickly. One guy mentioned, “There is more to life than studying and taking tests”.

I guess I get bored too easy. Let’s see, watch TV all night, or get to do something that’s intellectually challenging? You have to take breaks or you get burned-out, it has happened to me. That’s what weekends are for. Shoot, I love playing computer games and going out to the movies, but Mon-Thurs is all business for me. Come on, that’s very reasonable.

I’ve been doing Voice all day long at work for the last year, so this is going to be very helpful for me. I’m hoping for a quicker turnaround for the Voice (6 months at the longest). I’ve got to take the Voice written soon, so I need to look over the Cisco website to make sure I’m solid. I’m probably going to bypass the professional level certs for this one… I would rather focus on lab time.

IPExpert will be getting my business once again.

I recently bought some Cisco IP phones off of ebay so I could start my own VOIP lab at home. I purchased a 7940G and 7912G to start out with. The 7912G wasn’t too big of a pain; I basically had to reset the phone to factory defaults (no big deal thx to documentation online–and it already had SCCP). Well the 7940 was a different story. It was configured with MGCP firmware with a non-default password. I ended-up trying the two recovery methods on Cisco’s site. Needless to say, holding “#” while resetting didn’t work (it’s meant for SIP phones) and the “**#” didn’t work either (as it’s meant for SCCP phones). I was left wondering how I was going to get my 7940 working.

After google failed me, I came across this link
