Anyone implement their fire / intrusion based alarm systems over VoIP? These systems dial a phone number to the alarm receiver (server, etc.) and communicate a slow speed protocol between eachother. Worked great with the TDM phone system. Getting communication reliability issues when put on VoIP.
The "server" keeps printing out "data error" messages on an intermittent basis. Sometimes the alarm messages goe through just fine. I'd say it's 50% good / bad.
So, Alarm transmitter to VG224 port, H.323 over LAN to another VG224 port to the alarm receiver.
Worked with TAC today. The reliability is better but not perfect.
Just wondering if anyone had a GOOD experience with this. Otherwise, I will have to find another solution.
I know, why would you want to do this? Because it was on the TDM phone system and we have to try at this stage before the suggestions come out. There are also off-site
alarms that need to dial over the PSTN into the alarm receiver on campus, so it can't be avoided.
