Problem in outgoing internal calls

[tavorazo]

Problem context.
When you dial an extension of the same SIP account, the person who generates the call is NOT listening, the mute does not work
and Pause call does not work.

This scenario persists while the call is still active, even if the call is transferred, it is still not heard from one side.

SIP version: 0.7.8

Stage.
You are running this example and only the credentials were changed.

Extra.
If I frame an external number (example, cell phone) everything works perfect.
