The current module GSM Interface is UCM/GSM3.
The features of the UCM/GSM3 module include;
- Acts as a backup for dial-out on alarm activation when the land line is faulty or cut. Alternately, it can be used without a fixed telephone line, for installations where a telephone line is not available or not desired. Comfort\'s dialler can dial to 8 telephones which can include mobile or landline phones, pagers or Central Monitoring Stations.
- Allows the user to dial to the GSM number instead of the fixed telephone line to access Comfort Voice menus.
- Allows Comfort to report alarms to the users cellular phones via text message or SMS. The SMS message will show the alarm type and Zone description as text.eg \"101 Back Lane Road - 01 Intruder Alarm - 03 Back Window\"
- Allows users to send commands to control home appliances and the security system via SMS, and receive acknowledgement of the command by return SMS.
- Only authorised Mobile phones can send commands and receive messages from UCM/GSM3
Important Note:
The GSM network is subject to delays in the voice transmissions which may cause problems in dialing to Central Monitoring Stations which expect very tight limits on the delays between signalling tones. The UCM/GSM3 should not be relied on for the purpose of dialing to a CMS Receiver although it may be used as a backup dialer

Sorry I should have mentioned that GSM3 is using a different gSM manufacturer but otherwise functions are identical with GSMm2
UCM/GSM3 has been sold for more than 1 year already but it happens that there was no mention of the change
