[Asterisk-Users] iconnecthere problem 481 "Call Leg/Transaction Does Not Exist"

[pradeep kumar]

Hi All,

I am trying to use iconnecthere to make outbound calls. I am behind a 
linksys router. I keep getting this error
481 "Call Leg/Transaction Does Not Exist". Does anyone have any prior 
experience with this problem. Any leads will be much appreciated. Attached 
are the conf files and logs
