[OpenSIPS-Users] Can I read "$(avp(attr)[$T_branch_idx])" in "branch_route[per_branch_ops]" ??

[Rodrigo Pimenta Carvalho]

Hi Liviu.


Thank you.


That is the point I want to discuss!


According to the example from the documentation, the lookup() is in


route[relay] {

}


However, in my code the lookup() is in


route{


}


Even with lookup() in rout{...}, does it will populate the attributes of each branch in my "attr_avp" and I will be able to access them within branch_route?


Best regards!

Yes, lookup() will populate the attributes of each branch in your "attr_avp", and you can access them through $T_branch_idx within branch_route. [1]

Hi.


In my project with OpenSIPS, I have the following kind of code in the configuration:


modparam("registrar", "attr_avp", "$avp(attr)")

.

.

.

if register request come from machine M1 {

   $avp(attr) = "User in M1"; //this mean that the user is behind a NAT, from the point of view OpenSIPS.

}

if register request come from machine M2 {

   $avp(attr) = "User in M2";

}

...

else{

  $avp(attr) = "User in Mx"; //this mean that there is no NAT.

}




In my opensips.cfg file I need read "$(avp(attr)[$T_branch_idx])" in the "branch_route[per_branch_ops]" .


Does $(avp(attr)[$T_branch_idx]) will give me the correct value, even if the callee is always online in several machines (M1, M2...etc) ?


So, can I discover which machine is participating in the dialog?


Best regards.
