Hi, I have a configuration file where I am trying to send a stateful/stateless 480 response, after appending a RETRY-AFTER in the message header. But when I send the response back to the SIP enabled mobile phone, the server does not append the RETRY-AFTER in the SIP INVITE message header, when it sends a 480 response to the client UA. I have added both ethereal log and the cfg file. (you may wanna filter the log for SIP requests). Could you please tell me why it is behaving so and what is the way around it? Thanks a lot. <<ser_errors.cfg>> <<480ReplyT>> Thanks & Regards, Amit Singh Sony Ericsson Mobile Communications, 7001 Development Drive, RTP Durham, NC 27709 Ph: +1-919-472-1601
