How to use irules to do SIP outbounding proxy?

I think session command with keyword "any" may help.

 

call-id can be detected on the returning traffic by iRule and session command can be used to save persistence record, for example,

 

 

session add uie [list $sessionid any] [list [IP::remote_addr] 5555] $::sessionTimeout

 

 

(keyword "any" allows this record to be used by any virtual server)

 

 

I am not sure if the record that is being added by session command can be used by normal call-id persistence or not. (probably need to use appropriate syntax for address/port I guess) however, we can use "session lookup" command to lookup for the existing record also.
