Okay everyone...I have an easy one for you. I am trying to do a simple fail over from one ip to the other if I get a 4040 and it fails. Can one of you type the correct syntax for me. Below is what I am trying to accomplish. if (uri=~"sip:^1234567890.*@.*"){ prefix("1234"); rewritehostport("xxx.xxx.xxx.xxx:5060"); I need the hostport to be able to be rolled to another hostport ip if this one comes back with a 404 or any other failure. Can on eof you please help?
