Hi Guys, I am trying to make a call from a soft phone to a physical phone and for some reason the PBX responds with 400 Bad Request for the Invite generated by the soft phone. I have no idea whether the Invite violates any SIP ABNF. Below are the SIP messages both Invite and 400 Bad request. Any help would be greatly appreciated.
