I'm not a programmer nor script writer (working to correct script part) but I would investigate a script that could capture and record (more append) the voip packets to a file which at the same time...

This is all a theoretical exercise...
One would assume part of this task is getting to/at the voip packets. Physical access to the wire - insert a hub, MAC flood the switch, etc. a man-in-the-middle...

One thing stood out in a previous message...

The test equipment the telco used was T-bird equipment. They run 0's 1's and a mix of it...if they set it to Terminate they got all kinds of errors,...

If thats the way you think you can learn best then go ahead - personnally I agree and I'm trying to go down the same track (or as I say moving up the stack). May I recommend several tools to assist...

Recently received an email with a word in it underlined by a dotted red line....strange. Further investigation denotes this as a Microsoft 'smart tag'. Further reading (on Microsoft website) shows...

If anyone has seen and reviewed his (Lynn's) information - what impact does/would this have on the Cisco security products such as the PIX? I can only guess that the underlying IOS is similar in some...

DoS is a serious concern in VoIP networks. Its unlikely a vendors voip code will be virus infected (but you never know). As mentioned by Lansing you could separate your voip servers on a different...

You will need to treat the voip gateway pc as any other pc asset in the network (maybe even tighter security). Schedule OS upgrades and patches, install anti-virus (run it, upgrade it) and you should...

I haven't used the cisco vpn equipment but have used the nortel CES equipment in the past. If the cisco is as scalable as the nortel you shouldn't have expansion issues with either, its just a matter...
