the top of your heads, can you give me any ideas why calls to 911 would present
one way audio? I can hear the 911 center but they cannot hear me. There are 20
remote sites in different states with identical setups. Two out of the twenty
are having this problem. The others are fine. One is located in Sacramento and the other is in Edina , MN .
All scenarios utilize PRI and H323 gateways. Qwest is the carrier for both
trouble sites. There are other sites that use Qwest that work fine.</span></font></p>
