Routing UDP SIP responses to Via Address

The [SIP::via sent_by] is pulling the correct ip out of the Via, we can log it to syslog and it is ok.

 

The node [SIP::via sent_by] just isn't routing the request back to the ip.

 

If we do a TCP dump on the F5, the response UDP message is not being sent to that ip.

 

 

This may be a testing issue.

 

We are unable to recreate our real issue readily, so to test the iRule we inject a different ip in the Via.

 

Our syslog shows that we are passing this other IP to the node command, but the packet is still routed to the original client_addr.

 

 

Does the F5 disallow changing the ip to one that is not in it's list of "connected" clients?

 

 

 

Thanks
