>> As well as TCP DUMP attached. I’m having currently 2 machines with the Sylk, e.g. one on the old DEV version which perfectly works for both SIP and MSRP, and a single OpenIMS core. So the only difference now is that I’m using different application server IP address. The configuration of the working and non working version of Sylk is absolutely the same. Advises ?
