Phone and PABX Calls
General
The Phone Call allows you to call a landline telephone 
number or a cellular mobile phone number. The Private 
Automatic Branch Exchange (PABX) Call allows you to 
call local (office) extension numbers. This type of call needs 
to be activated by your Service Provider.
In this publication we use “phone number” when referring to 
these numbers.
Both calls have the same dialing features.
For operating the MTH800 in RF sensitive areas, see 
“Transmit Inhibit” on page 39.
