From the packet information you pasted, it seems your SIP client doesn't meet the RFC( 1341,2046) requirements.

This is the reason of the problem.

Follow the RFC correctly.
----------------------------
Each part starts with an encapsulation boundary, and then contains a body part
consisting of header area, a blank line, and a body area.

Check the RFC again.

"boundry" must be "boundary".
