Thanks John, appreciate all the help you provided.

Yes we can have an external database which will link the station MAC address with the extension.

But how do I get the station MAC address associated with my PC?

Yes the approach mentioned below is what I would like to go. My problem is how do I get the extension X and the Mac address of the phone in my application?

Will I get these details from any packet which my application can capture?

Thanks for your quick replies.

I want my application to log the user to his/her extension to the IP Phone when they log in their workstation and logoff to the original extension when they logoff their workstation. As their workplace keep changing they will be connected to the IP Phone on the desk they are seated, which means they will have different Original extension and MAC address. Ofcourse the New extension will be one for each user.

If I want my application to use the command
enable ip-registration old ORIGINAL new NEW mac MAC

my application will have to first retrive the ORIGINAL extension and MAC address of the IP Phone to which the user workstation is connected to.

How do I retrieve the ORIGINAL extension and MAC address of the IP Phone to which the user workstation is connected to?

If I understand correctly once you have SA8520 license runing on AES, from my client application I need to run the command below to change station default extension to logged user extension.

enable ip-registration old OLD new NEW mac MAC

Document says that MAC is optional, does that mean it will be detected automatically by the Communication Manager from the old extension as the station is already registered with the old extension?

Which command will log off the station to default extension?

Thanks John

Hi John,

Even I am trying to achieve remote station login/logout. Can I also request information about SA8520 via direct email?

Thanks,
Priti
