My company has an Ip telephony network, that consists of 3com NBX, PIX fire wall, and fail over fire wall, Cisco switch, IP telephony sets, and cisco routers,

Remote sites are connected to internet through SDSL cisco routers, but they can’t talk to each other, while any remote office can talk to main office, and vise versa.

If a remote office tries to call another remote one the other will here the ringing, but once he tries to answer, they can’t hear each othe,

Is there anybody can help suggesting some possible reasons.?

Hello, can anybody explain to me these dBs:

1. dBrn
2. dBa
3. dBrnC
4. dB0
5. Transmission Level Point (TLP)

I am reviewing in telephony and how do these things differ with ordinary dBm (decibel relative to 1 mW).. How to convert these dBs mentioned to dBm? thanks

Everything, and anything, I use, including, Paint, calculator, firefox…etc, wants to delete this. My firewall alert pops up saying things are trying to delete it. I press allow, and it still tries to delete 5 minutes later, sometimes with the same program. I looked this up, but I couldnt find anything usefull on this exact problem. So I thought id ask, and maybe someone knows what the heck this is.

The router was working with the old modem. Since comcast installed the new modem (voice overIP), it stopped working. I even tried the 30 sec. restarting process.
