Netgate SG5100 and Qos (SIP)

[hebein]

Hi,
just moved from 3100 to 5100 abd I am lost: How can I set my SIP/VOIP-traffic to highest priority?
pfsense says: The specified number of connections is greater than the number of ALTQ-capable assigned interfaces!

Regards,
Gunther

Any hints? I am lost... I need priority for VOIP/SIP in one of my outgoing WAN-interfaces.
