[OpenSER-Users] questions about 1.2

[Cseke Tamas]

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
