Akka timeout on VoiceInterpreter for Dial scenarios

[hrosa]

This exception is very common when running Dial scenarios:

04:00:53,920 ERROR [org.restcomm.connect.interpreter.VoiceInterpreter] (RestComm-akka.actor.default-dispatcher-111) Exception while waiting for outbound call info:
java.util.concurrent.TimeoutException: Futures timed out after [10 seconds]

@hrosa The above error is not suppose to fail a call as it happens only during the dial action which is executed after Dial is finished. The issue you report is for a timeout when RC tries to get call info from outbound actor which happens to be terminated.

What version of Restcomm you use for load testing. The patch committed here d89890e protects and prevents this error.

@gvagenas I've been testing against branch that was recently merged against master. I see the patch was submitted 16 days ago.
Let me re-run tests and check the outcome.

This test was run yesterday (Feb 14), all calls were successful but there is still some Akka timeout issues in RestComm log (12 occurrences).

Also, isn't 10 seconds too much waiting time?

@hrosa I guess we have a race condition here, I will check that

The 10 sec is quite high and will be reduced, but actually I plan to remove Akka Ask pattern all together #1401
