Hello, I am Benoit and I am working on the SER and the server and the database is working well. The problem is when I try to registrer SIP agent, the error message is "Error 483:" Too Many Hops". In the file ser.cfg there is a function mf_process_maxforward_header("10"), and the problem is that I don't know where is this function and how does it testing the max forward header because the SIP agent that I use set this field to 70. Kind regards Benoit
