CVP 4.0 SIP CUP Failover

Unanswered Question
Jul 16th, 2008


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

2100050* pri/wei 2/50 hop

3100050* pri/wei 1/50 hop

3100050* pri/wei 2/50 hop

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 have this problem too.

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!
