hi 
i got ccme router 2800 and pri line.  CCME 3.3
intermittently my pstn calls are disconnected.
there is no error under E1 controller. it happens randomly but i dun know wh
y. 
do you think it is because of there is no qos in the switch: i created voice
 vlan and data vlan but did not configure any mls command.
also what is the message        DisconnectCause=1Fwhen i run the command sh 
call history voice  id 

phone loads: 7.2(2.0)                7940/7960 
phone app  load ID   P00307020200

ccme upgrade or qos or phone firmware? 
thnx

You might want to look at output from 'debug isdn
q931' during a disconnecting call.
