10.0pt;font-family:Arial;color:navy'>We have some ADEMCO fire alarm panels that
use DTMF tones to communicate and use DTMF tones with bursts of 50msecs, so
that eliminated VG248’s since their fastest DTMF sample size is either
100 or 150ms, so VG224’s were purchased. Most of our gateways that
were MGCP capable were configured that way, but the MGCP config for the ports
that these fire alarm panels were connected to weren’t working, so I
tried H323 and it worked. Since I have setup these ports I have tried
modems on similarly configured ports and have gotten better, more reliable
performance from the H323-configured ports than the MGCP-configured ports.
I don’t have any technical explanation of this, just my own experience.<o:p></o:p></span></font></p>

Unless your environment/customer has a specific<br>

other, use with what you're comfortable I'd recommend.<br>
