2. Are they set to a receive coding method that matches your send method? Try
changing Codec settings while they listen.
3. Try changing the Codec: Bitrate and redialing. Some connections will pass one rate
but not the other.
4. If you're working in stereo, make sure both ISDN lines are connected. If one of them
hasn't been dialed or has dropped the connection, they won't hear a single channel
of audio — instead, they'll hear nothing at all.
If they can hear you but the pitch sounds wrong, the Codec: Sample Rates probably
don’t agree.
More troubleshooting tips appear later in this manual.
17: How do I send a test tone?
Open the Audio submenu and then one of the microphone’s submenus. The last item in
each mic submenu lets you turn test tone on or off. Then adjust the routing and level
using that microphone's controls.
wNOTE:
G.722 relies on the audio signal itself for synchronization, and can have problems
with steady test tones. If you're using this coding method, avoid using the tone
generator.
18: How do I hang up?
pPress the DROP button. A screen like this will appear:
One or both lines will be automatically selected, depending on which are currently
connected. Tap the EDIT knob to hang up, or select just one line if that’s all you want to
disconnect.
Pressing DROP doesn’t do anything if neither line is connected.
