[OpenSIPS-Users] bug in SST module ?

[Samuel Muller]

hey back,

I checked only the problem during the state 2 (ringing) of the dialog, sorry.
For each state of the dialog, there are others variables added by SST,
and many of them are not well encoded :

i.e., during state 4 (in call) these vars are :

value:: accX_table = acc\nvalue:: accX_flags = >\x06\x88\x08\nvalue::
accX_aaa = \x12\nvalue:: accX_log = \x12\nvalue:: accX_leg =
\x02\nvalue:: accX_core = \x06\nvalue:: accX_created = "\xf4\x98P\n

hope it helps,
