[OpenSIPS-Users] bug in SST module ?

[Bogdan-Andrei Iancu]

Hi Samuel,

It seems that SST is adding some dialog variables (attached to the 
dialog) which are not properly printed when calling the dlg_list_ctx .

Could you post (on pastebin) and network capture with the HTTP response 
from opensips ?
