Hello,

I use latest openisps 1.8 by follow sheme:

opensips 1 (11.22.33.44)-----> opensips 2 (77.88.100.100)

When opensips 2 receive ACK I see follow problems:

1. In trace debug 6 I see message:
" DBG:sipmsgops:sip_validate_hdrs: duplicate header 'Content-Length' "

There is not duplicate header.

2. The ACK messages not find dialog parameters.

Here is debug 6 :
