Hi, This may seem like a silly question, but I would just like to know if any modifications need to be made to the routing block(s) of openser.cfg to allow calls to be established using TLS? I'm running openser v 1.1.0 and I have just setup TLS. I'm using SIPp to test it and it seems to be working as I can register using a SIPp scenario. However when I try and make a call the invites are challenged and authenticated, but once that is complete the invite is not forwarded to the uas. The uas is registered and listening using TLS. The SIPp scenarios also work perfectly if I don't use TLS. Am I missing anything?
