Lesson learned!! a

We ware implementing PLAR/Hotline whatever you would like to call for some very, very important person and department. We tested PLAR configuration on test phone and everything works fine. Now time to deploy on production environment.

Well, for the sip phone you need to have a sip dial on the phone. But nobody knew you have to define which line button you using PLAR and apply a SIP dial rule on that button.

So we deployed and all call made on those phone was going through the PLAR destination line.Untill know body knew sip dial rule have to defile which button you using for PLAR..... It was such a disaster :D
