Created by: Levent Ozturk on 25-02-2013 09:56:01 AM Hi everyone, We have a custom directory service that is working fine on 6941 and 8945 but we have problems when with 9971. Whenever I make a search in the directory service with no criterias given (no name, no surname, nothing) I always get a "HTTP Error [500]!" error. Where can I start to look for the problem? Thanks for your help. Levent

It looks your web application has a problem to serve the phones request. Try to check logs on the server (eventlog, ...). Mirek
Subject: RE: Re: New Message from Levent Ozturk in IP Phone Services (IPPS) - IP Pho Replied by: David Staudt on 26-02-2013 10:00:47 AM Some models handle un-specified input values differently. For example, with a input fields 'requiredValue' and 'optionalValue', if the user submits the screen without putting anything into the optional field, the phone may request either: GET /myService?requiredValue=something&optionalValue= or GET /myService?requiredValue=something
This makes a difference in the server-side script, as 'if (optionalValue=="")' might work for the former, but won't for the latter (the optionalValue param was never received and is 'undefined'.) You will want to check if optionalValue!=undefined before assuming it has any value (including empty string)

(We enabled debug on IIS but did not receive any request.) Thanks
Subject: RE: Re: New Message from Levent Ozturk in IP Phone Services (IPPS) - IP Pho Replied by: David Staudt on 27-02-2013 10:03:42 AM The behaviour is phone/firmware specific and not configurable. Just a guess as to whether this is the actual problem. We can perhaps gain some more insight by comparing a network packet capture of a working vs non-working phone - and of course identifying the nature of the failure in the application script (on IIS?) would be the primary troubleshooting avenue.
Subject: RE: IP Phone service not working on 9971 Replied by: Mert Yeter on 12-03-2013 10:04:55 AM Hi David, I captured working and non-working phones packets. I discovered that if I didn't give any value, phone makes GET requests without adding parameters, so I get http 500 error. Working phone (6941): GET /PhoneService.asmx/GetPhoneBookResGM?firstname=&lastname=&title=&departmentname= HTTP/1.1 Non-working phone (9971): GET /PhoneService.asmx/GetPhoneBookResGM HTTP/1.1 HTTP/1.1 500 Internal Server Error Missing parameter: firstname.
Subject: RE: IP Phone service not working on 9971 Replied by: David Staudt on 13-03-2013 12:54:44 AM Yep, so your script will need to handle this possibility, i.e. parameter being missing results in the same script action as if parameter is missing but null/empty
