[OpenSIPS-Users] Opensips generate two Content-lenth headers

[Oleg Podguyko]

I’m using opensips as proxy. I got INVITE from one side, do some logics ,remove ISUP body and send INVITE to destination via dispatcher module.
And I see that outgoing INVITE has two content-lenth headers. Remote side after received such INVITE sends 400 
Bad Contenth-lenth header.
