[OpenSER-Users] questions about 1.2

Hello,

We are switching from 1.1 to 1.2, and i have some problems.

1) Could you please tell me how should i handle natted contacts in regisers. i read modparam("registrar", "nat_flag", 6) is not exists any more i guess i should use nat_bfalg in usrloc module, but i don't know how to use this, could you tell me an example? how should i set the branch flag which should be used for this?

2) There is no Calling-Station-Id and Called-Station-Id in radius accounting packets. Although i use the same libradiusclient_ng.so, with the same configuration files, and the same radius server too. I need these attributes, could you please tell me why they are missing?

Thanks any help, Tamas
