VRP: VRP 3.4 0201P13
Voice call hang up after sometime.
When using SIP for VOIP in the AR28-11 for phone calls through SoftX, the SoftX sends a OPTIONS requisition to the router to check if the call is still up. The router does not respond to this requisition. After no response the SoftX will send lots of OPTIONS requisitions for 2 minutes, if no reponse, the SoftX cut the call.
There is no solution to this problem in this VRP.
Route Engine must be upgraded to solve it.
There is a restricted version AR28-VRP340-F0305 that solve this problem.
