How to use irules to do SIP outbounding proxy?

Hi,

 

Did you make this work?

 

We do something similar and have found out some things that can be good to know for anyone trying to load balance sip.

 

 

For me it felt natural to use mode because I was working with sip but that did not work together with keyword any

 

Example

 

On vs_1

 

session add sip [SIP::call_id] [LB::server addr] 180

 

session add uie [SIP::call_id] [LB::server addr] 180

 

 

On vs_2

 

session lookup sip "[SIP::call_id] any virtual"

 

This do not get back the stored value

 

session lookup uie "[SIP::call_id] any virtual"

 

But this do..

 

 

Simply use uie instead of sip, but it is strange that it did not work with mode sip.

 

 

 

Another thing that can be confusing is that when you choose a sip profile in your vs you will get the SIP::call_id as persistence value even though you choose None as your Default Persistence Profile. I'm not sure this make a different but we created a SIP persistence profile that never match and used that insted. With this we only have the values we set and want to use.

 

 

 

All this is valid for 9.4.3, I do not know if it is updated in any hotfix or in 9.4.4. Does anyone know?
