Getting a strange PING from you Cisco Call Manager? Dropping every 6th packet?

We have been having some issues with our Cisco VOIP system here, such as phones rebooting, SRST Fallback messages etc. During the troubleshooting process I discovered what I thought was latency with the route to the Call Manager:


MDF1#ping
Protocol [ip]:
Target IP address: 192.168.XXXX
Repeat count [5]: 100
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 100, 100-byte ICMP Echos to 192.168.22.1, timeout is 2 seconds:
!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!
!.!!!!!.!!!!!.!!!!!.!!!!!.!!!!
Success rate is 84 percent (84/100), round-trip min/avg/max = 1/2/9 ms

We got on the phone with Cisco, replaced the adjoining switch to no avail. Upon further investigation we discovered that this is normal and has to do with the firewall policy. Cisco CUCM and other VOIP products(CUC) use a rate limit on their firewall to protect against DOS attacks, and we can safely ignore this:

admin:utils firewall ipv4 list
***output Omitted***
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED

Does my baby pee too much? There's an app for that!

Have you wanted to know how healthy your baby is based on the content of their urine? If the answer is yes, then you are in luck! Seriously, a company based in New York called Pixie Scientific has come up with a "Smart Diaper" with a QR code that you scan once a day with their smart phone app. Once scanned it will send the results to Pixie Scientific for analysis. The immediate goal of the program is to tell of:

- urinary tract infection 

- prolonged dehydration

- developing kidney problems

The program isn't a go yet, they still need some funding help. Once funded they can begin manufacturing, testing, and eventually FDA approval.

Copy + Paste (Clipboard) Issues / Not Working With Windows 7

Some users are having a problem copy and pasting with Windows 7. The problem seems to be consistent with multiple applications. If you have a valid recent System Restore, Microsoft recommends this as a first course of action. If this does not work, use the System File Checker to check you system. Access SFC by:


1. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

2. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow. 

3. At the command prompt, type the following command, and then press ENTER:


sfc /scannow
