FORCED DIAL 
A useful feature of the Intercom panel is its ability to call a number sent to it in a text 
message. This feature can be used when setting up the SIM card. For example, disabling 
the voicemail facility or disabling automatic SMS messages or missed calls. Any number 
up to 15 digits can be called and the call will last for a maximum of 40 seconds. The 
example below would switch off voicemail on a Vodafone SIM card. Substitute the 
Vodafone number for other service providers (See important note on page 18). 
1111DLE”1210“    Dial 1210 for the intercom panel 
Other useful numbers which can be used with this feature are as follows. Please also 
check the service provider’s web sits for other useful codes. 
Vodafone O2 
Disable voicemail  1210  1760 
Disable text alerts  #148#  1760 
NOTE: Disabling voicemail and text alerts is very important as there is no way to retrieve 
either of these services from an intercom panel. Disabling these features will also prevent 
the intercom panel switching to voicemail or sending a text when dialling in from another 
phone. 
STORE SMS AUXILIARY MESSAGE 
When C2 & AI are shorted on the intercom panel, a text message will be sent to the 
number stored in memory location 020. The text message can be customised using the 
following message(See important note on page 18) :-
