Hi.
My problem is the next. When my sip server send the message INVITE to the phone, the phone always respond with 400 Bad Request, I think is something wrong in the message, in the UDP message the Checksum always is corrupted by the sip server, is it the problem? or is something else in the sip message? How I can correct this?
this is the trace:

Hello,
I can't see the Content-Length header, maybe is not displayed in your trace or is missing and this could be the problem. See what the caller sends to OpenSER.
Cheers, Daniel
