[Spce-user] No audio in any direction

I am testing an SPCE v 6.5.2 in an OpenStack environment. The environment is
very similar to Amazon AWS.

I have an internal IP with NAT 1: 1 with external ip.

I have configured advertised-ip with my external ip.


When I make a call between two users of the SPCE, the call is processed but
I do not have audio in any direction.

After 60 seconds there is a timeout and the call hangs up.

I have seen that the rtpengine gives an error when booting:

ERR: Failed to set thread scheduling paramaters to 'default' (-1) / 0:
Invalid argument


In addition, the log of the rtpengine registers the following: 

Dec 5 15:49:12 spce (info) rtpengine [28912]: [1544021352.067490] INFO:

I see that the SDP reports the external ip.

Any ideas?
