[OpenSIPS-Users] Need help on flag in usrloc

[ha do]

Hi Bogdan

got it :)

1 more question about the flag 
modparam("nathelper", "sipping_bflag", 7)
 modparam("usrloc", "nat_bflag", 7)

the modem ADSL will close the port after 3 mins(some minutes), so Opensips should send OPTION message(sip ping) to modem to keep port that should open for UA 

the sipping_blag of nathelper module should be the same value as nat_bflag of usrloc ? or the cflag of usrloc just  has a value??


Thank you
Ha`

Hi Ha,

the NAT branch flag you use is 7 (nat_bflag) and in usrloc you find the 
branch flags in the cflags (contact flags) field. The cflags is a mask 
with all the branch flags: 192 = 128 (2^7) + 64 (2^6)

Regards,
Bogdan
