Wireshark · Ethereal-users: Re: [Ethereal-users] Question regarding ISUP within SIP messages

["Olivier Biot" <ethereal@xxxxxxxxxx>]

Hello Michael,

I had a look at the capture file, and have to say that the packets have a 
bogus ISUP multipart entity: the ISUP payload is dissected as an HTTP (or 
SIP or MIME) *header*, as the separation between header and body is lacking. 
This separation is an empty line, like can be seen in the 1st entity 
representing the SDP payload.

Best regards,

Olivier
