[OpenSIPS-Users] SIP/2.0 400 Content Length is Incorrect

[Bogdan-Andrei Iancu]

Hi Julien,

To be honest, in 90% of the case, a "smart" ALG is guilty for messing 
around with the SIP messages. Try ngrepping the request when going out 
from OpenSIPS and when being received by "PArtner" and see if "pix" 
screwed it up .

Regards,
Bogdan
