Hi, so I have a pjsua module for python. Everything works fine except two things: I can't find any solution to replace important for my job parameters: Replace FROM header. I found one solution but its obviously bad: acc = lib.create_account(pj.AccountConfig("sip.diamondcard.us", "481341", "148317354153","Bruce")) where Bruce going to From header. But I dont really want to register every time if I want to change a caller name. I tried to put it into header_list in acc.make_call but my headers appends in the end so nothing changes. Second one: How to catch if other side answered a call? Because pj.CallState.CONFIRMED doesnt seems like a legit way to do that. Thank you!
