> We have a setup with 2 redundant stateful SER SIP-Servers with 
> accounting. 
> 
> For calls to the PSTN we have 2 ISDN-PRI gateways connected to 
> different ISDN-PRI lines. 
> 
> We need to implement a dynamic failover mechanism and load balancing. 
> 
> a) Incoming calls: No problem, the PSTN switch takes care of that 
> b) Outgoing calls: 
>   Both GWs are registered at both SERs; calls are usually relayed with 
> "t_relay_to_udp(x.x.x.x, "5060");" 
>   But how can I implement a quick failover including load-distribution 
> between those gatways? 
>   I.e. if I receive "busy here" or no response after a short period 
> after the "invite", the call should be redirected to the other GW.
