My OBi110 setup with Google Voice & Alarm System Works but other problems
Stewart:
Your alarm system probably has at least two numbers for the central station. If one fails, it tries the other. If you don't have direct access to the panel programming, ask your security company. The system may be somewhat more robust if the two numbers are routed through different providers. For testing, you could force a call to the first one to fail, so you can confirm that the backup works as expected.
You panel should make periodic test calls, e.g. weekly, to the monitoring station. If it fails to communicate, there should be both a local indication (keypad beeping or siren chirping) and a notification from the central station. Unfortunately, most systems won't inform you that the primary number failed, if the backup works, so you may want to occasionally review the logs.

That's a great idea to have each number go through a different provider.
Some alarm companies warn you that, as was noted previously, VOIP is not reliable for quality communications to an alarm system. Switching to cellular is a good idea, but usually costs more. Some companies have reliable internet connections setups also.
