How to : Edit large wireshark files with “editcap”

Wireshark does not play well with large pcap files. I read somewhere you need 1GB of RAM for 1 GB of file.

I recently needed to review the contents of a 30gb pcap file and wireshark refused to open it.

Few minutes of googling and i came accross this useful command

editcap. Its part of wire shark, located in the installation directory

editcap -h will give you some useful information

I found this post useful

Here is my example for extracting one days worth of capture

“C:\progam files\wireshark\editcap.exe” -v -A “2019-30-11 08:00:00” -B “2019-11-30 18:00:00” c:\input.pcap d:\output.pcap

How to find the oldest file in a certian location

I wanted to find the oldest recording on the local hardrive.

How to use screened transfer on the nupoint


Recently i can across my first customer using “screened transfer”. The facility had stopped working correctly after an upgrade.

The calls were being transferred but no questions were being asked of the caller and the receiver of the call was not being asked if they would like to take the call.


After further upgrades and checks i was told that i should check the supervised transfer settings. It needs to be s+xg

Oaisys E1 Audio PCI-E board

Found some useful settings today which i don’t think are in the manual.

There is a control applet in the control panel.

audio board 1


With this you can change the card from T1 to E1, aswell as some codec options.

If you leave the card in default it will show T1 Oaisys.

To change to E1 ports you need to open the applet and set as below.

Visual voice in MiCollab client and NUpoint

Just had an issue where some of the MiCollab clients could not see their voicemails in the visual voice window.

I knew I had it set correctly as all accounts were using same licenses and FCOS

The client icon would change in the system tray and a tape reel icon would appear in the top right hand of the client but know message in the window

Besides this issue the client worked fine

What I eventually found out was that all clients that were working had Windows Media Player installed. WMP.

I saw in the release notes that it is a pre-requisite

The “N” version of windows does not have MWP installed in default but I believe you can add it on manually

The version the customer had was “Enterprise” but it had no WMP. May be a custom install image was used.
