Hi! I would like to know how can I add a custom field to the registration's Via header. If I try to connect to my server it refuses the registration with internal server error. If I try to connect with an other client I can do it, so now I'm checking the differences between the two REGISTER message with Wireshark. First difference I found that the other client put an "alias" field into the Via header. Does anyone know what is for "alias" field and how can I add it? sry for my english bye, Attila -------------- next part -------------- An HTML attachment was scrubbed...
