IP Phone Warehouse - Tech Tips

Tech Tips at IP Phone Warehouse

Asterisk may not work correctly if the X Window System is running at the same time.

Insert the command:

# ps aux | grec X

Stop the X Window System if it is running.

Still problems? Review the DMA levels on the PATA IDE hard drives.

The drives should be set to UDMA2 mode. If they are not, use caution in resetting them, as hard drive corruption could occur if it is not done correctly.

Hearing an echo can be solved a number of ways.

Reboot the system, ensuring all hardware and software loads correctly.

Check the equipment. Most often, it is not the card that is causing the problem, as everything that passes through the card is digital. The echo has to come from somewhere else. A VoIP or analog phone may be causing the echo, as well as an analog line. You may need to test the phone equipment, or call the analog and VoIP line provider.
