             Summary: WaitExten(5,m(default)) broken IAX2 channel
                 Key: ASTERISK-21918
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21918
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 11.4.0
            Reporter: Dmitry Burilov


When a call comes through IAX2 trunk he gets on WaitExten application.
If the specified class WaitExten musiconhold, the call is dropped.
ex. WaitExten(5,m(default)) -> IAX2 call is dropped.
The problem exists only when calling from IAX2 trunk.
When you call a SIP trunk in the same context, there is no problem.
