Hi, I set: modparam("cpl-c","proxy_route", 10) and in route[10] I set RtpProxy if flag(5) (NAT in the caller) or bflag(6) (NAT in the called) is present. But unfortunatelly the bflag(6) is never set when usingCPL. For example the following and very simple CPL: <cpl> <incoming> <lookup source="registration"> <success> <proxy /> </success> </lookup> </incoming> </cpl> I understand that the operation of CPL is "encapsulated" and so, but since we can spec some parameters as: modparam("cpl-c","lookup_domain","location") modparam("cpl-c","lookup_append_branches", 1) why then can't bflags be loaded? If it is not possible then I can't use <lookup source="registration"> and need to do, neccesarialy, a spiral with: <location url="sip:SAME_USER;cpl=no"> <proxy /> </location> and don't apply CPL in the spiral incoming message if URI has "cpl=no". Any explanation of this limitation could be really great. Thanks a lot.
