No audio in calls between realms with srtp-msm-passthrough enabled.

Hello

When user registered in realm Access-IECI-INT-MEX  makes a call to user registered in realm Access-IECI-INT-PER

  or viceversa, the call is established but there isn't audio in both direction.

Each realms have been configured with TLS and SRTP with srtp-msm-passthrough enabled in order to not anchor the SRTP media between devices

The media release configuration in realm has been  configurated of the following form:
