Hi everyone,

I've been away from SER for a long time but now I have renewed interest.

I'm confronted by a problem I've failed to solve by my self, maybe you could help, this is regarding accounting and what happens when a customer responds with a 3xx response (i.e. redirect).

Call from customer to proxy works fine.

Accounting works fine with START, STOP

Call from PSTN to customer, works fine, I have choosen not to generate a START record to make it easier for the billing department.

Here comes the tricky part.

Call from PSTN to customer and customer has redirected his extension to a PSTN number.

This call generates no accounting (not even with setflag(1) at the top of the route block)

I've managed to trigger the 'Redirect prohibited' message by using onreply_route[] but I find no way of canceling the request there.

What I want is to be able to either disallow 3xx responses completly or by selectivly cancelling them in onreply_route.

Another question, my ser-users archive just broke and I haven't been able to do much searching, what's the best way today to handle several pstn gateways and loadbalace between them for outgoing calls?

Best regards,

Thomas Björklund
