Are you setting the pool in the rule in the CLIENT_ACCEPTED event? If so, can you disable address translation on the virtual server and test the following rule:

 

 


when CLIENT_ACCEPTED {
    Check if the SIP method is NOTIFY
   if {[SIP::method] equals "NOTIFY"} {
      node 1.1.1.1 5060
   }
}

 

 

Replace 1.1.1.1 with the actual pool member address. I think this should allow you to hard code the destination IP and port for SIP NOTIFY requests only.

 

 

You might also want to add a monitor to the SIPApplicationServer_pool and use logic in the rule to check that the pool is up before setting the node to use. You can use [active_members SIPApplicationServer_pool > 0] to see if there is at least one member marked up.
