[Serusers] Multiple SIP - PSTN Gateways

[Tirpák Miklós]

Hello,

I was looking for the same script at May 2003. You can find Jiri's and Jan's 
answers in the archive, the thread is "forwarding unanswered call - once more". 
Sorry, but I could not try the script, because the backup gateway was required 
for another project. I hope I will do it in some month.

I am also interesting in load balancing. Do you plan to extend the capabilities 
of SRV dns query? I mean supporting of multiple SRV records: load balancing in 
case of equal priority values, failover with different ones. Can this be a 
solution for both problem?
