Two of the newest additions in OpenSER development version got the attention in the last time.
First is about SCTP (Stream Control Transmission Protocol), a contribution of Connecticut College, completes the list with transport protocols supported by OpenSER. SCTP is mainly used for trunking, hopefully will gain more space in end-user side as well.
Second is about benchmarking your configuration file. The new module benchmark brings the necessary tools so you can wrap a piece of configuration file and get the execution time. Elements that can have decisional impact in scalability and tunning.
