Hi, I am not too sure about this but can you check the syntax of the from and the to header fields in your invite,is nested addr-spec allowed in rfc 2822,because once the local and the domain address are both resolved can the parser continue parsing another nested angled bracket?

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.
