[OpenSIPS-Users] bug in SST module ?

[Bogdan-Andrei Iancu]

Hi Samuel,

Those values are actually added by ACC module when doing dialog-based 
accounting, not related to SST actually.

I guess the mi_xmlrpc module should escape the non utf8 chars -> I will 
mark this as a bug.

Thanks and Regards,
Bogdan
