Hello, Is there any reason the CentOS 6 RPMs don't build utils.so or http_client.so? Looking back to 4.3 it appears it was being built: kamailio-utils-4.3.6-1.1.x86_64.rpm However it is no longer available in 4.4 nor 5.0 RPMs for either CentOS 6 or 7. Thanks, -- Trevor Peirce AcroVoice Solutions Inc
