By default, as a security measure the IPS2000 authenticates whether an IP phone is allowed to log on by ‘tagging’ the MAC address of the device (softphone nic or IP phone) and then this remains attached unless the phone is logged out using the dterm logout feature.

This causes problems because if a phone that is logged in is simply ubplugged, switched off, or the user tries to login on another phone, it will not allow another mac address to be assigned to that extension.

There is another way though.

You can tell the PBX to use PIN numbers to authenticate the user as the ‘owner’ of that IP extension and this will then allow you to use the protected login feature, which allows you to login anywhere, whether you logged off the original phone or not and it will ‘follow me’.

You have to allow protected login on SRC15 or put the phone into a class that allows it.
