Hello!

Thanks! But I stayed with the LB-module and CacheDB-local. It works well!


Best regards!

Re: [OpenSIPS-Users] Load_Balancing

[David Villasmil]

Agreed, just go with dispatcher (I usually do random, which distributes the
calls pretty well)

Re: [OpenSIPS-Users] Load_Balancing

[Vadim Dumalekov via Users]

Thanks!

I have one more question. Why can't the dlg_val be set in this case. 
This variable (dlg_val) is not passed to the second INVITE, although it is a 
SIP Dialog (INVITE -> 401 -> ACK -> INVITE ...)

Re: [OpenSIPS-Users] Load_Balancing

[Bogdan-Andrei Iancu]

Vadim,

The 2 INVITE requests are not part of the same dialog, so you cannot use 
dlg_val's - each initial INVITE is creating a different dialog.


Now, if you really want, you can rely on the fact that the 2 INVITEs 
have the same call-id and and use the cachedb_local to remember which 
Ast box handled the first INVITE. But this somehow will invalidate the 
whole idea of balancing calls.

Re: [OpenSIPS-Users] Load_Balancing

Hi,

Considering the fact that Ast_2 cannot perform auth on a challenge done 
by Ast_1, you should re-consider the routing logic in OpenSIPS, and not 
to use LB, but rather dispatcher with hashing over call-id for example.
