[OpenSIPS-Users] Second call on transferred with B2B refer scenario

[Bogdan-Andrei Iancu]

Hello Santi,

There is nothing attached and it is not a good practice to have large 
attachments on the mailing lists (as you are flooding the inboxes). 
Better uploade your trace on a pastebin like side (or store pcap on 
ftp/http servers) and just post the link.
