I am having a very strange issues, basically i have 2 routes in my CUPS Proxy, one to each VXML gateway one with
2100050* pri/wei 1/50 hop 10.1.69.2
2100050* pri/wei 2/50 hop 10.146.15.2
3100050* pri/wei 1/50 hop 10.146.15.2
3100050* pri/wei 2/50 hop 10.1.69.2
both work to the pri 1/50 comoing from their respective call server, but if I reload one of thhe gateways and send calls through it never goes to the next VXML gateway!! :(
Any ideas what I am doing wrong, maybe some timers somewhere?
I figured out the issue was only when the gateway had no connectivity. Changing the following service parameters on CUPS resolved my invite problem
Maximum INVITE Retransmissions default is 6
and I changed it to 1
Retransmission Timer -T1- (ms) default is 500 changed it to 300
Failover between VXML Gateways and call servers is working like a charm now!
