[asterisk-users] misdn issues

[Zaine Pretorius]

Hi,

I'm having issues where people call one of my ISDN numbers, and sometime, when 
we answer, the call is dead. Its only sometimes happens, like one in 15 
calls. I have analogue phones pluged into a mediatrix and a couple of pap's, 
and these connect to the asterisk server. Please could someone help me with 
this issue.

## extensions.conf 
[from-pstn]
; Incoming ISDN Calls
exten => _X.,1,Answer()
exten => _X.,n,NoOp("DNID = " ${DNID})
exten => _X.,n,NoOp("CALLERID = " ${CALLERID(all)})
exten => _X.,n,NoOp("EXTEN = " ${EXTEN})
exten => _X.,n,Dial(SIP/${EXTEN})
