ok.. i am reviewing the logs now

Can you pls suggest which type of membership do i need to buy? Basic membership also can ask technical queries based on purchased hours. And then there is Support enabled membership. Also, can you suggest which tier does my query fall in? As they specify that Tier 3 & Tier 4 category of questions need paid technical hours?

The AVAYA server is handled by a third party vendor. I will ask them for logs. The frequency i think will not matter because the same dll is being used by their older application which when tried doesn't fail when the user logs in.

Hi everyone,

Could you help me with the following issue?
I am using AVAYA IC 7.3 version. I have a .NET WCF application hosted in IIS which is sending request to AVAYA for user's login. I am supplying the necessary credentials, telephony extension number the URL where our AVAYA server is hosted. However, this function throws back an exception stating "Object reference not set to instance of an object". This doesn't happen all the time.. but it happens sometimes for 5 to 15 minutes and later it again starts working. I want to know if there is anything i should need to correct in my code.

At times, when I try logging into AVAYA server, it throws back an exception stating that "Object Reference not set to instance of an
object". This exception happens only sometimes and continually for some time. If I retry my request after 10 - 15
minutes, I don't face it again. I supply the necessary credentials - user name & password and also provide it appropriate workstation number and AVAYA server's link in all my requests.However, on some occasions only, I receive this exception. Does anyone have any idea of this?
