I am using OpenSER 1.0. When I send the following to the FIFO: ----------------- :ul_add:ans location 81(a)dev.skyridge.com sip:34@sirloin.skyridge.com 3600 1 ----------------------- I get the response "400 ul_add: replicate expected". I have done a google search without finding anything helpful. Can anyone explain what this means?
