Hello Steve,

 

 

LB must respond to those request because of availability check, if MSS recives less than 50% answers then particular MSS node, which was sending requests, will mark LB like "down" and won't send any SIP traffic from that MSS node.

 

I don't know if F5 is responsible for this issue, that's why i need advice. Customer thinks that this issue has something to do with me/LB since LB is the one not answering to all requests, but i don't see how i can influence on those responses to OPTIONS requests sent from MSS.

 

SIP health monitor I use on LB to check Rhino servers availability is working perfectly.

 

The same thing is done from MSS side. There is health monitor from MSS side towards LB and there we have minor issues(only for some calls) i posted in earlier post .

 

So IP are following:

 

Active LB 10.21.28.93 (Public IP subnet) ----|

 

|----- VIP address 10.21.28.94 <<==>> 6 MSS nodes (10.21.50.6 - 10.21.50.11)

 

Standby LB 10.21.28.92 (Public IP subnet) ----|

 

I hope i explained problem well.

 

 

Regards,
