Primus does not endorse using VoIP for security monitoring, although some TBB users have had success.
TBB user Bruce setup a system using a proprietary format called Contact ID from Honeywell/Ademco. He could not get this to work at all, since it communicates in DTMF "touch tones" and there was too much echo on the line (at the time).
He also tried the "SIA" format (Security Industry Association). This is a universal format generally regarded as the most modern. It worked after he activated the "fax" option for his TBB line (by calling Primus) - SIA generates modem-like signals rather than DTMF touch tones.
