The emergency phone(s) in my setup seem to be experiencing low microphone.
If your setup includes consolidators and an Iwatsu PBX, there might be volume issues where the
microphone volume of the emergency phone is low. Test different GAIN settings to achieve
optimal results, but note that if the gain is too high, the DTMF may become distorted and make
the PBX unable to route the calls. Adjust the voice gain setting to achieve optimal volume. You
may first want to try setting the VOIP-1-2-4-8 field units to:
VOICE GAIN: +5db IN, -5dB OUT
Also, increasing the trim pot on the emergency phones may help.
The attendant phone(s) cannot pick up microphone input from the emergency phone(s) in my
setup.
Ensure that all Emergency Phones are programmed to operate on Mode III.
My configuration changes are not saved in the VOIP unit.
After each configuration change, make sure to hit OKAY at each screen, and do a “save settings
and reboot” when you are done. If you do not click save and reboot, all changes will be lost.
